i need abit of advice on this......what you think it may make on the motor, and how hard this would be to tune

ZZ4 shortblock possibly, think its 9.6 to 1 comp with 64 cc
comp cams XFI efi cam 218/224
trick flow heads 195cc
accel superam base
AS&M siamesed runners.

base on my searching around, i think that should be good for mid 12's, puttin out about 375hp or so, and pull to 5500rpms. which is where i want it to be

maybe i should try for 10 to 1 or abit higher compression...
what about regular AS&M large tube runners?

if i do go siamesed runners, should i siamese the base at all?

 

EXACT SAME combo last year. Best I could muster up was a 13.4 @104 I had the ASM runners, but I did also have the stock converter and stock chip.

It dynoed 276 RWHP and 324 TQ

 

See my signature. Similiar set up but with Trickflow heads and ZZ9 cam which is smaller. I should be in the mid 12's by the end of the year with a little tweaking here and there.

 

is the 218/224 cam too big for a 350-357 motor with fully modded TPI?

i would like to think it would work great with AS&M siamesed runners and my accel base

maybe i should just fork out the 750 for superram uppers

 

No. People here in SoCal are running the 218 degree cam with modified TPI. I'm looking into the XFI cam myself. If you get the proper Trickflow heads with the double springs you can run the XFI cam. Allen

 

yeah thats what i figured, it should make good power

that set-up should have easily put you in 12's
im runnin stck block heads and cam with that intake set-up and pullin 13.5's

 

Oh i know, but it didnt lol.

 

When I had just the intake stuff done like you, 14.1 was my best.
