Hi. I'm looking to build a gen 5 454. Carb. Looking to get the most hp I can on pump gas. I have .088 heads,air gap dual plain intake,quick fuel m-850 DP carb. It's going to be bored .30 over. Probably port and polish the heads. Need Pistons,cam and lifters still. Will be running MSD dist and box. I will be getting exhaust also that will work best. Would like silent choice compatible anything you guys suggest or add would be great.

Unless your doing the head work yourself it's not going to cost much more to get a significantly better set of heads. Sell your 088's and upgrade if your truly looking for the most you can on pump gas.

THat little box in the upper right corner that says "search" use it, there are 45,321,912 threads on 454 builds. decent heads and cam/valvetrain your a little over 500 hp which is nice , dependable and should be drive friendly.

The two in bold above won't work together.

Decide which ypo'll ditch and then we all can go from there.

Im staying out of these 454 builds from now on. For some reason, they bring all the heat.

It sucks that the guys that actually build motors get bashed on here. I like the budget builds. As a first time powerboater their info is essential to my DIY builds. It seems on a 454 the current trend is peanut port heads, a rectangle port mismatched intake. Joking aside I also would like to see a stout na 454 build.

Actually Joe he is going .030 over so he's not 454 anymore. Have at it.

It's a great topic that has been addressed a lot but seems to bring in a lot of opinions, and some people only see one recipe for some reason. There are a lot of ways to do it and guys willing to share. Maybe PM a few of them and what they think. I called 4 different builders and talked to them for a while. Then made the best decision for me.
Good luck with your build.

Whip it is true hit the search button and you will find many builds such as yours, but the people that have already posted know a lot about engines and how to build a solid engine. I would read more and even pm some of the members lots of knowledge on OSO.

Good luck

Well, in that case! lol

Seriously though. Silent choice exhaust is going to limit the camshaft you are going to be able to go with. My personal opinion, is forget silent choice y flappers. We have plenty of sound solutions that can reduce noise, without the reversion issues of silent choice flappers.

The GM heads are going to limit your potential. I'm not even going to touch base on cylinder head talk, as I do not want to wake the bears.
