I figured that i would ask to see what some major things would get me this hp

1. 302 Blocked bored .40 over with stock style pistons.
2. Ported gt40 heads with 1.6 roller rocks
3. Gt40 upper and lower intake
4. 75mm throttle body with egr
5. 24# injectors
6. 76mm maf
7. Shorties with off road h pipe
8. Aftermarket Fuel rails
9. 3.73 gears.
10. .512 Custom ground lift cam

Would that big of a cam work with gt40 heads? i didnt know because i cant go over .510 with trick flow heads. let me know. thanks

AndySpeed

why cant you go over .510 with trickflow heads? i thought all there heads had a valve spring to hold .600lift? id hope a aftermarket aluminum head could handle more then .510

w8less

no its just an explorer motor with a cam. and you don't need the aftermarket fuel rails the factory ones will be more than enough

dthompson67

ok. well i was told that i couldnt go over the .510 lift amoutn. chek on page 2 or 3 i posted what pistons will work for trick flow heads and one guy said he called and asked and that is what they said.

TB needs to be 70mm, and no. I'd guess closer to 250rwhp on a setup like that

I don't see that setup breaking into the 300 HP range. Essentially just swapped the top end with a few other things.

To compare it with a similar swap.. People who install the Trickflow top end kit (H/C/I) usualyl end up with 285ish RWHP.

r.barn

probably not

Get youre gt-40's ported by thumper. cam by jay allen for the cam,bump up to some 1.7 rr's and you MIGHT break 270-280rwhp.

You guys are seriously underestimating what you can get with GT40s. I've seen dyno sheets all over the place. Common numbers are 280ish.

samseed101

If that's the case, i wouldn't say we are underestimating anything then. Two out of three of us said numbers in that range.
