You would also drop a bunch of weight if you had the aluminum 496 manifolds. I'm curious since I have stock 454 mags in my Scarab and would like to try and squeeze 40 to 50 hosepower potentially out of each engine.

If I take it easy, the alpha's might last. If not, it is easier to get the insurance to replace outdrives than engines.

How will the insurance co. find out that there is more horsepower? Will they dyno the engines for me? I plan on keeping it stock looking (keep the q-jet, 496 exhaust manifolds, not sure which cam or intake).

I am running the 496 stuff on mine, I make about 450 hp, Iw as told by alot of people that they support up to 500-550 hp easily.
The 496 Manifolds are actually pretty nice, seperate runners into a big 4" riser

Good to hear as I already have the 496 aluminum manifolds and risers. Just need to polish the risers and complete the install. What did you use for your shift cables mounting? I aso have remote mounted oil filters off of the stock manifolds too.
