This may be lengthy to explain but it will do justice to what I'm trying to do.

I have an AMC 360 in my garage that I'm working on right now.

The college of Engineering's Drag Race Motor is a BB Chevy 454.

I'm going to rebuild both of these, but I would like to see what benefits it would be to put the AMC in place of the BB 454. From sheer numbers alone this looks like a stupid feat... but I'm seeking your advice none the less.

Further,
I will be writing a proposal for rebuilding the 454. What parts sources, and/or suggestions, and pitfalls would you reccomend that I keep my eye out for.

ON the other hand I will also be presenting a proposal to take the AMC 360 and build it up in place of the 454. What are the benefits/defficits of replaceing the BB with the AMC? And what parts would you reccomend that I put or at least look into, to make the AMC as formidible as the BB?


Here are some further specs:
Current State of the BB 454:
It is a DONATED 454, Bored 0.060 over. Last dyno pull that it made, it didn't pull over 300 HP - something sounds wrong to me here too -
The guy who built it, didn't build it for a drag application, didn't balance, didn't polish anything. So basically he put a new cam in it - I dont know the specs right now - otherwise its a PLANE JANE rebuild.

Although we are a drag race team, I doubt that we'll push over 6,000 RPM for a while.

Transmission is a 2 speed Powerglide

The AMC... other than haveing a cast crank and rods, the rest of it can be built to almost any specs. So here lets hold very little back. I had plans for it being a street engine, but if I can sell it to the team, and keeping it under 6,000 RPM, the cast elements shouldn't be a problem. But Ok I know you guys are going to suggest a 401 crank and rods... lets assume that to be accepted that when I find a 401 crank and rods I'll get them. OK well what else would a Drag Race built AMC requre?


-Thanks in advance

How about going radical?
I don't know if Program's 4bolt main caps work on the 360 (they were designed for the 401), but that would give you a solid bottom end for a 401 crank (or Moldex 401), ch*vy BB rods and pistons to match a set of 4.374" sleeves to put you at 500CI w/4.150 stroke.
INDY is pulling 800hp out of their aluminum set up with a similar build, running stock heads you could probably get around 700hp w/o even adding nitrous.
