A friend and i are building a 350 with edelbrock e-tec alum heads, like vortec heads and using the edelbrock air gap intake.

The block is pre-86 (non roller cam) but the cam we'd like to use is the ZZ4, or actually edelbrock 2108.

From what I can figure out, we need to use special roller lifters in pre-86 blocks, and they go for some $450!

Is there a hyd flat tappet cam that has specs similar to the ZZ4?
-deg: 286/286 (int/exh)
@.050 218/218
@cam .350/.350
@ valve .525/.525
Open 3 ATDC/41bbdc
close 41abdc/ 3 btdc
center 112/112

I have found a cam or two that are close, but the open and close 'times' and total lift are not the same.

There are just TOO many cams out there and i am going insane reading cam specs at this point!

Thanks for any help or direction!

other specs:
(compression about 10:1, 600 cfm 4 bbl, automatic.
in an 84 camaro. street use/weekends and fun.
