the ZZ4 cam.
I got a question from a member at vetteforum.org ( swedish corvetteforum ).
"Is it a good combo to install a ZZ4 cam in a ported TPI setup. With headers, and 1,5rr. And what springs to use with that cam?"
Whats your toughts? Will the TPI choke the hell out of it?
Thanks..

Re: the ZZ4 cam. (devilfish)
I use this cam with large tube runners and base, r/r , exhaust etc. I like this combo :D I have gone 12.84@108 in my 90 auto coupe. i use 113 ported heads and the lt4 springs with no issues i do not rev it above about 5200 rpm
My best ever 60 ft was 1.89 most are 1.91 to 1.95
I have just fitted headman headers and a converter and it feels like a different car easy 12.5's i think
:cheers:

Re: the ZZ4 cam. (devilfish)
They are ASM runners which are the same ones tpis sells but $100 cheaper
My best 1/8 time is 8.11@86mph it pulls hard upto about 90mph c5's are easy from a standing start, but i guess we would be equal from say 50mph upto 100mph after that i think i would get left behind but i don't know for sure.
This is before my latest mods which i have not tested at the track yet.

The zz4 is relatively mild cam compared to the 219, 211 or zz9 cams. It would work fin even with a stock TPI c4. You will need valve springs to handle the addition liuft of the cam, though

The TPI might choke it off a bit, but once I finish opening the intake (K&N, cut lid, modified MAF) I don't expect there to be problem. The car runs incredibly strong with this combo and the stock chip.
Long tube headers are going on shortly and then with a new chip I'm expecting quite an improvement over an already good thing.

Re: the ZZ4 cam. (1MoorTym)
I am using an Ed wright "Mail" custom chip at the moment. Runs nice but i will be investing in some scanning software soon to see if it can be improved.
I have no issues at all, but i just can't leave it alone in case i am missing a 10th or 2 :D
