52mm throttle body.
World products 64cc comb. chambers
2.02 intake & 1.66 exhaust.
1.6/1 roller rockers
Stock TPI intake. ( it has been ported and polished)
The cam is a custom ground Lunati.
lift - int.452 exh.465

lobe separation 112 degrees
valve timing int. open@ 0 closed @ 47

Rob,

We already talked via e-mail but I'll post here also.

Basically, you have a 305-383 swap. Here is what you want to do....

Get a chip from a 1989 Corvette with manual transmission. Change the bin via a program like TunerCat to use 30lb/hr injectors. That's it. That is your starting point.

After you get it running you will probably want to dive into the MAF tables and the WOT PE vs. RPM table. But, that is AFTER you get it running.
