Ok, my L98 is dead. Time for a new motor.
I have the 350 all ready to go in, but before it goes in, i'm thinking of going with a ZZ4 cam, with the L98 heads. Has anyone ever run a ZZ4 setup with the stock TPI? How did it work?

------------------
1980 Camaro, '88 Police 350 engine, Headers, full exhaust, completely redone, my baby!
1988 Iroc-Z L98, MSD 6a, Accel coil, K+N's, Airfoil, Coolant Bypass, Flowmaster, Gears, Late model Bose, I like the 80 better

 

I have that exact setup with some porting and it works excellent, very fast and for some reason mine has a great top end as well as low

 

Check my mods. BlackIroc- whats you 1/4 and mph? What mods do you have? Or is it a secrete?

------------------
Mods: ZZ4 engine w/stock TPI, adj, fuel pres. reg., MSD 8.5, HI6S ign. w/ PS-91 coil, K&N filter, TPI air foil, Hooker comp. shorties, American Thunder flows. 160* stat., TB bypass, 3"cowl, bat. relocate, AC delete.

 

What do you guys run in the 1/4 with your setups?

I haven;t brought it to the track but i want to know what most ets and mph are, also what tranny is backing your zz4 i have the wc t-5 and it is holding up well thus far I drive hard sometimes but not all the time

 

I got the WC T-5 as well. It needed a rebuild before I put in the motor. It still does. I manage to get down the strip @103mph in 13.700 sec. The 1/8 in 8.7sec. Thats on 255 street tires.
