Hi
Im building a 383 from a 350 87 to 94 block


I have a 88 gta tpi now 305 t5


and I have everything about to build 383


I just got a set of bad *** alum heads custom made from a local shop


and they told me I may need longer push rods


he said stock or .100 to maybe .200 longer


now I don't really want to buy 2 sets of longer pushrods for nothing


can anyone tell me for sure if stock ones may work


im using my friends shop and its costing my money to use his shop


and if I get stuck with the stock ones not working I would have to wait weeks for new longer ones


I thought I would ask

You should use a 5/16 pushrods checker. Stock roller cam is 7.200 flat tappet 7.8

 

ok and how hard is it to install new melling oil pump


do you need press or does it bolt in

 

Bolt on, the pickup will be a press fit.

 

get an adjustable pushrod length checker and then you will know exactly what you need.
