My ol'e LT1 bit the bullet. I wanted to install a new motor but I need recommendations on different combos and parts. I have a P600B and wanted to install it on the new motor. I would like to go 383. I was thinking of boosting between 12 and 15 PSI. Would I need all forged internals? what parts manuf. should I go with/avoid? Also What can I do to the stock heads,manifold, etc. to ready them for this type of duty? What size injectors?

Thanks

 

Your best bet would be to do a search. There is alot of useful info out there since this question is asked all the time. I think you will be pushing it if you plan to see 12-15lbs out of a P600b.
