427 SBC, American Speed?

I Haven't used the bowtie block on that deal.I found in the past the gm stuff to be very good with the exception of the lifter bores from years ago which I'm told have been fixed.There Castings look really nice.The one thing I can warn you is on a Dart block And it may be the same on the Bowtie is that if you look at the sleeves where they have flats on them on the corners theres a little water port that the gasket sometimes doesn't cover very good and the water will fiqure eight around all the sleeves and run up the studs to give you a milk shake.So I'd watch for this.

Thanks Tom! I'll be checking in with you in about a year or so for a twin turbo. I still have to assemble my C4 chassis and I'm old and slow!

All the info been a big help Tom. Once I get a more accurate time frame for taking the car down to DSE I'll now when I need the engine. It sounds like you have a great rep and do great work which is what I've been looking for. Thanks again, Steve.

most of the people building ultimas over here in the uk are using AS engiens! they are what the factroy "recomend". there have been quite a few reocring problems (most with overheating thanks to poor carb setup).

try www.pistonheads.com/gassing/ and go into the Ulitma section. ask around in there as everyone is very friendly.

hope this helps some.

Chris.

check out this web site: www.millarengines.com, in the gallery there is a section of street machines with some nice engines. there is a dyno sheet from a customer with a 427. Is actually only 427 .030 over. Pump fuel engine for his going to be every day driver Chevelle. There is also a fuel injected 604 Donovan in a '55 chevy

i've seen some outrageous (as high as 1.14) correction factors on AS engine dyno sheets. You get what you pay for. We build engines too.
