70 or 75?

[mustangjoe87]

Im about to buy a typhoon and T body. Should I get the 70 or 75? They are the same price, I'd rather grab the 75. This is for a combo im putting together that includes an M90 setup (8-10psi) still looking for what heads and cam I want.

70mm.. thats what i run.. and i will be running the same as you with the M90 and typhoon.. lol

75. There was a HUGE debate about this either on here or the corral, do a search and you'll see.

Really does depend on your setup, but if you are going to super charge then go with the 75.

Prolly going with a set of tristate gt40 heads, f303 cam, and typhoon intake.

 

[ms93gt]

They are 500 bucks, Dont really have 1000 in the budget for heads

$500 assembled?

I would save a little more and get some TW's or AFR heads....You would definatly feel a difference, especially once you get supercharged

 

[mustangjoe87]

Yea 500 assembled with porting

Id love to buy AFR's but but total budget is 1100 and just heads would wipe me out if I bought them.

I got my trickflows brand new for $800. Save the cash and buy a good set of heads.

1k for used heads. i wouldnt do it.

gt40's are not that bad of heads. if thier freshly ported for only 500 i would get them.

 

[1SLO306]

blah, why gt40's?

gt40's that ported will surpport a M90(only push about 5lbs or so stock) if it was a s/c like ur i would do the TW or 185's.

if u plan to upgrade then get the tw or 185 but if not the ported gt40's will do just fine

Your kidding right. Those 185's are 1,200 new, with rockers easily 1,400. He's saving a good penny, plus please find me a set of afrs USED for less than a grand.

For his heads, yes gt40s do suck. Forced air is forced air, either way he will need a good flowing set of heads. Plus why skimp on one of the most crucial parts to the top end? What if he plans to upgrade in the future? He's going to be pushing 10lbs, not 5.

What if he plans to upgrade in the future? He's going to be pushing 10lbs, not 5.

i stated that if he plans to upgrade then get the tw or 185's but with all the fab work u have to do to run the m90 i dont think he will upgrade anytime soon maybe never. thier are not many 5.0 with the m90 cause all the work u have to do.

here is a thread about it. a eaton m90 made 290rwhp with stock heads, lower intake, headers and so on. so the gt40's will do fine as stated before
