what you guys trapping with a simple gt-40 combo. lets say this is your set up

-GT-40 heads
-Cobra intake manifold
-e cam
-long tubes, catless x, catback
-cai, underdrive pulleys 70mm throttle body and 75mm mass air.

whats a basic trap speed for that setup? also is there a better intake and off ther shelf cam for that combo?

edit: forgot this will be in a 94gt 5 speed

there are plenty better cams then the E-cam, somebody else can tell you that. You might want to look into a performer or Performer RPM intake. But I don't think you are gona trap much more then 104/105 or something in that area or probably less???

yeah i figued 105 at best was going to be my trap with that setup. guess i should go with some trickflow heads. i want to trap around 109-110. i know thats on the high side. if anyone is selling some good aluminum heads let me know

I only went to the track one time witn my 306 pre-blower set-up.

Stock compresion
TW heads
Anderson B-31 Cam
RPM intake
70mm TB
LT's O/R H-pipe
3:73 gears

I think I trapped around 108ish with not much pratice on worn out Nittos

My brother has GT-40 y303 aluminum heads with an E cam and Holley Systemax intake, Shorty headers and 4.10's on his stock 302 and he has trapped 111.8. I ported the heads though, thats why his combo runs so good.

damn i trapped 102 on my 92 lx with 130k miles on the motor. 3.73 gears, pulleys, shortys, x pipe, catback, throttle body, mass air, and and cobra manifold

Daniel, that combo should do 105-106, as you mentioned...

Substitute the heads for AFR or TFS and port the Cobra lower, lose the e303 and get a custom or a better suited OTS cam and 110-112+ is possible.

Your brother also trapped 105 with the same stock longblock that Daniel had in his 92 and went 102.

Lightweight cars can be deceiving ;-)

yep, it's been down over a year I think now, broke a bolt in the timing cover, broke an ez-out in that bolt, can't get it out.

he then bought and rebuilt another shortblock (rings and bearings) and it's just sitting in the garage, ready to bolt the oil pan on and heads/top end.

I dont live close enough to go over there and drop it in for him either [Mad]
