New member here, but have been reading this forum for awhile.

I have a 98 Formula 6-sp

Old setup was:

lid, hpp-3, T1 cam,TTS headers, 3" Random Tech catback, Isky gold springs, Ti Ret., Hardend Push rods, susp. all the way, ripper shifter.

It put down 378 rwhp and 363 rwtq.

New setup is going to be:

Slp Ram Air, 85mm Maf, ported T.B., smooth bellows, pulley, LS-6 intake, FM-11 on a 112 lsa, offroad Y-pipe, and LS-1 edit done by a pro...

I am hoping for the 400 hp club if not a little more.

Let me know what you think?

Thanks

This is still on stock heads. Wanting to see what I can get out of them before the next mod.....Heads!

Any suggestions!!!

Cam specs are 228"/230" .581"/.591" on a 112 lsa.

Thanks

I would think 405-410

I see you have the F4 how do you like it?

Im just putting it in now with my headers. I had a B1 and liked it. I decided to do both at the same time. I think im going to like it.

What kind of numbers did you do with B-1?

F11 here....but w/TEA 5.3's....and all the bolt ons. I would think you'd see
405/390(ish) on stock heads .... keep us posted!

formu8

Will keep you posted on the outcome!

Just seeing what I can get out of the stock heads!

Sounds like an interesting setup let me know how you do!

formu8

Do I have to go with the 5.7 heads because of the perimeter bolts?

Or can I go with the 5.3 heads?

Which one would perform the best?
Thanks

And what is the cost going 5.3 heads?

you can get the 5.3's but you'll need the centerbolt vavle covers and the coil pack brackets as well. comes to about 160 or so IIRC.

formu8

So, will 5.3 heads perform better than the 5.7 heads?

The cost is no big deal. looking for the best performance!!

FM11 TEA Stg 2 5.3s here. 5.3s have a great exhaust port. Also 5.3s have a smaller chamber for more compression without decking and lost P to V clearance.
