Hello fellow hotrodders are you ready to make more power and save money? Then here is a great deal on the ultimate street/strip manifold for the 86'-95'EFI Ford 5.0 V8. This manifold has a fully Ported and reshaped lower (not just basic mild port work or sanded smooth) and a partial ported upper that gives you the best of both worlds. The upper has been partially ported to enlarge runner exits,eliminate the restrictions in the runners,throttle bodyopening is increased and curves blended. The lower has been fully race ported and reshaped. The lower has an average flow of302 CFM and the ports are straight enough you can pass a 7/8" long socket thru them!!! With it's upper bolted on top , together it's average flow is 269 CFM which is more than the top 5 aftermarket manifolds in it's class. After my port work these manifolds are 3lbs lighter! These manifolds have a lot of work into them andare nothing like what you would get with a mild port job. They Flow a lot of air to allow for more power.
This manifold flows 45% more than a stock GT40 and will support more than 545 FWHP with supporting parts. Most heads for the SBF don't flow 269 CFM at the max lift of the cam so this piece will work very well with just about any combo.
With this manifold you won't lose any of the low/midrange torque and power that you loose with the aftermarket ones but will make more average HP than the top 5 manifolds in it's class (I have flowed many aftermarket manifolds on the same flow bench to comfirm this).This manifold is great for the grudge cars or the sleeper cars because you can makebetter than aftermarketpower but have a stock look. A motor doesn't care what brand name is on the manifold it only cares about air flow, CSA and runner length and if you get those right then you make more average HPAnd that means a much faster car!!!
Ported to accept up to a 75mm TB but will work with any size smaller and with a runner size CSA of 2.25" (the System Max II has a 2.47 CSA but only flows in the mid 240s CFM). SBF TrickFlow 170heads have a CSA of 2.01" and flow 233CFM at .500" lift out the box so the MYTH of the GT40 manifold being too small is WRONG with my ported GT40 manifolds.When they compare a STOCK GT40 manifold against the aftermarket manifolds it's always down 25-30 HP on the top end but up 30-35 ft lbs of torque on the low to midrange. Well my Ported manifolds match and better them on the top end and better them on the low-midrange also for a lot less than what they are going for.With an extremely broad power range from idle - 6,700 RPM with the proper supporting parts. The manifolds are first steamed washed, sandblasted then painted with high-temp ceramic paint in silver color (if you want black or a combo color like in the pictures just add when ordering). This manifold is hard to beat and is drilled and tapped for the ACT (air sensor).
A great choice fora street/strip302, 306, 331 and 347 size engines.
Don't be fooled buy other so called ported GT40 manifolds that are just cleaned up, sand smoothed andhaveNO Tested Flow data or track times to support their claims (there are somebasic cleaned up manifolds out there claiming to be Race Ported so be aware). Not all manifolds are ported the same!My Race Portedmanifolds have more than 20 hours of professional porting and flow testing done tothem so it is provenwith solid data and track times (I have sold and ported 100s of manifolds and heads, all with great results). It will make more average power from idle to 6,700 RPM than the top 5 manifolds in it's class. Why buy a stock unported GT40 manifold that only flows 180-190 CFM when you can have a one that flows 270 cfm plus with my Race Ported GT40??? Combos running my Race ported manifolds and stage 2 ported GT40/GT40P heads are running low to high 11s with bolt ons. Combos running my Stage 3 heads are running faster than that. I run my own ported parts on my cars and have one of my Race Ported GT40s and Stage 3 ported GT40 heads on my full weight 91' GT with heat, AC, power everything, AOD with 3500 stall and full interior that runsbottom 11s on pump gas with no power adders!!
If you were to take a stock GT40 manifold and have it ported and flowed to my specs by another Pro porter you would pay over $750 plus the price of the manifold!Why pay$500.00-$750.00 for an aftermarket manifold that flows less and makes less averageHP?You can have a custom ported and proven manifold that out performs aftermarket manifolds that cost more. Many people that run a stock GT40 soon find themselves upgrading or falling short of their goals because they want more power, why settle. Get the good one the first time and be done with it. I can get these manifolds to out perform any aftermarket manifold in it's class with no loss of low end or topend power. Don't miss out on this one by waiting. You don't wantto get caught at the lightsWITHOUT a Race Ported GT40!!!!!
Some customer results:
"So now that I've seen for myselfwhat your ported manifold can do I am a true believer. Not only does my car pulls like crazy all the way to my 6,500rpm redline but it even sounds different, meaner. You really take pride in your porting and now my buddys fear my lil fox body" Bill J. from Oklahoma City, Oklahoma.
"Your manifold put out the goods. For the price this is a steal. The runners are really big and You were right, I can fit a 7/8 long socket through all of them even runners #1 and #5!! I'm very impressed" Craig J. From Oak Lawn, Illinois.
"All I could say whenI took my car toour localdyno was wow! I had no ideaaported GT40 manifold could perform that well. The torque was higher and I gained 31hp and 800rpm more over my old manifold. You did way more work for the price you charged. Thank you and I will be back for more port workin the future" Robert C. from Chicago, Illinois. (He has a 331 with TrickFlow heads, Stage 2 cam, 75mm TB and full bolt ons. His old manifold was a stock cleaned up GT40 manifold)
"Went out to the Track 3 days after I put your manifold on and on the first pass I beat my previous best time buy3 tenths of a second. By thesixth pass I was 4 tenths of a second faster than my best before the manifold change. I knew by the looks of the ports that your manifold was going to flow a lot more air than my stock GT40 manifold" Trevor from Englewood, California.(He had a Stock GT40 manifoldon his combo and the only changes was adding my Race Ported GT40 manifold. He sold his old GT40 to get back some of his money spent for the Race ported)
"Tony my 90' LX put down 352rwhp at 6400 rpm with your Race Ported manifold and my TFS heads that you ported. I beat my brothers combo by 14hp but saved over $1,000 more" Doug from Levonia, Michigan. (His brother uses AFR 165 heads, Performer intake and E-cam with 1.7 roller rockers)
"Hey buddy, with your Ported GT40 manifold,that stage 1 Trick Flow camandcleaned upGT40P heads my 1992 Mustang GT went [email removed by ] mph. Didn't think I would gain that much over my other manifold but the timeslips don't lie" Chris from Goose Creek, South Carolina. (He ran a 12.08 with a Professional Products manifold before he installed my Race Ported GT40 manifold)
"Tony I got my Pony's new numbers. With your all out fully Ported GT40 manifoldshe put down389rwhp and 380wtq but was running out of fuel after 5700RPM. She made more hp and tq than my Eddy and nowI need bigger injectors because we think she has more in her"Mike from Jacksonville, Florida.(He has a 10:1 347 with AFR 185 heads, Anderson cam, and other bolt ons. I cut, shortened the runners, welded and fully ported the upper and lower of a GT40 manifold for him that replaced his out the box Performer RPM that he sold. With the right injectors his combo should pull to 6400+rpm and make 10 to 15 more hp)
"Wow! It looks like you ported this manifold out with a Jack Hammer! The ports onthe manifold match up great with my AFR 185s and oh boy this little 302 just keeps pulling way past 6200rpm now. You did a great job on this manifold and you're going to be the only guy that ports any of my stuff for now on" Bob from Elmwood Park, New Jersey. (He has a 1988 Mustang GT with a stock bottom end, AFR185 heads,F-Cam, and other bolt ons. Old manifold was astock GT40 with no port work)
Send me your Ford, Chevy or Mopar manifolds and heads that you already own and we can port them from mild to wild. I get stock valve GT40s and GT40P headsto flow 230/167cfm @ .600" and with 1.90"/1.60" valves to flow 245/200cfm @ .600"
GT40 manifold porting labor starts at $200.00
Iron head porting labor starts at $425.00 a pair and Aluminum starts at $400.00 a pair
My full all out cut and welded uppers and Lowers flows over 325 CFM, has short runners tuned for 7500 RPM and is cheaper then the TrickFlow R manifold that flows in the mid 290 CFM range. It's geared for the higher RPM stroker motors!
