427 SBC, American Speed?

[buck171]

I'm looking for a 427ci small block chevy with about 550-600hp for an early nova. The 427 from American Speed seems like a good set-up. Anyone have any experience with them, good or bad? Thanks for any input.

I do know where you can buy a complete turn key and dyno tuned engine for cheaper than that. Check out www.speedomotive.com . Nothing wrong with american speed, but i do know guys running speed-o-motive engines and they seem to be happy with them.

I personally had a very bad experience with Speed O Motive. The 540 big block they built me had so many things wrong with it that it was impossible to believe. I ended up reusing only the block, crank, and rods, and had the rest rebuilt from scratch, after which the motor made 150 HP more.

It's just like anything, there can be a lemon in everything. Like i said i know guys running them with no problems. When the 502 was the hot ticket a good friend of mine bought a ZZ502 and upon fireup and the first 5 min of run time it manage to throw a rod out the side of the block, never took it over 2000rpm. The only thing he put on was his carb he had bought. It happens.

Hey buck171 -

Give Tom Nelson a call at Nelson Racing Engines (818) 998-5593.
Tell him what you are looking for and he will build it. He is a sponsor of this site and does nothing but top notch work and will stand behind it.

P.S. I see that this is your first post. Welcome to the board !!

Look under the Classifieds section.
You will see Namtra is trying to sell a 400+ hp 350 for a killer price.
Just throw on some power adder and you would have your 550-600 hp for a great price. Just a thought.

You can't beat a Bill Mitchell 427 for the money and warranty. I have 2 of them in my camp, one dynoed at 546HP, the other 561HP E mail me at [email protected].

Hey Tom. I'm curious about the same thing. What's the difference for a Fuel Injected motor with an aluminum block?
I'm always looking for different power options.
Thanks
Mike

If you do a search for Speedomotive on most all car sites you will find more horror stories than you can imagine. I'd say 10:1 bad to good. I have my own story about them but I don't feel like typing it out. I would avoid them like the plague.

Any company that sells you a 750 HP big block "dynoed" engine and will not guarantee it makes even within 50% of that (plus doesn't dyno them anyway other than on a computer program) does not get my vote. The amount of poor machine work, balance issues, oil useage, etc. will amaze you.
