Re: 454 build?
By far your best value is to purchase the 502 HT crate motor from GM part #88890534;Brand new,warranteed for 2 years;no oil leaks;hydraulic roller cam;just add a dual plane intake and edelbrock carb.You cant beat cubic inches in a tow vehicle ....I would not even put headers on ...they leak and pop gaskets after a while ...just put a good dual exhaust on.
Nice truck ....77's are a one year truck with the yellow in the trim
