I got myself a 1 Ton GMC 3500 moving van for a pretty good price, and am thinking about building the 454 in it up to put in my Chevelle......Yeah I know.. I posted this over at Team Chevelle, but the guys there did not really have much to say about it.
My main question is.... CAN I get some good heads for this thing for cheap.....OR will the heads on it be suitable for mid 11's?
Does anyone elese have any input on this Gen V 454
What specifically are you looking for? The BSE specs are pretty thorough on the components and would work for Gen IV or V. The stock heads are probably peanut port heads so you'll need large oval heads. 215s and 063s are pretty good closed chamber ovals but they have the smaller valves. By the time you buy the heads and have them built your well on your way to buying a good set of heads.
You're correct on the heads being a problem. For a good street motor I'd go with a set of the Dart Iron Eagles or a set of the Merlin Iron heads. By the time you take a stock pair of heads and recondition the valve guides, enlarge the valves, buy a new set of valves, etc., you've wrapped up a pretty good chunk of change in the stock heads. If you want to go aluminum take a look at the edelbrock heads. They seem to have a pretty good price point.
