If I don't change the cam when i do the convertion is it really going to hurt my performance? Also I have a couple of high performacne vette heads off my Dad's L82 vette. They are 1.94/1.6 valves and i was thinking of porting and polishing them instead of getting the AFR's. Will they bolt up to my 89 block? and will my 86 TPI work with the heads?

 

I believe so, you should be able to use your dads heads with an 86 intake. The heads should bolt up as well.

The cam you have in your car is the same as the stock cam for the 5.0 TPI Automatic, so your performance will be ok. If you simply put in an SLP Cam then you could really benefit from your mods.

Word of wisdom from experience IF you have an 86 PROM, ditch it and go with something newer. I programmed my own and used the ARAP Bin from an 89 Vette.

Thanks for the help. The reason i was asking is because I tought the 87+blocks had center bolt heads and 86 and down were a diffrent style.

 

the block itself is the same. the only difference is the angle of the center intake to head bolts and the bolt location on the valve covers. the head to block bolts are the same on all small blocks.

 

Thansk for the reply sofa king!!! LOL
