$10K for an all aluminum small block? I wish mine was $10K, not even close. I don't buy the financial argument at all, team shelby put in whatever they thought had the best chance of winning, it's all advertising and sponsorships for their products. I bet those 351w were $30K motors if not more.

AL,
Those cars were in a spec series so why would TEAM SHELBY care about winning when they ran against each other. I think they were iron blocks with aluminum heads, not sure though. If it is a spec series you usually try to minimize cost where ever possible. I think Bob B. has a Superformance with a small block in it which he really likes and might just influence his opinion.
I see you are in Scotts Valley, if you are out and about Sunday the
25th of May why don't you come by the Marina airport off reservation road.
I will be running an autox there and you will be able to see and hear a fairly quick reving big block. If you have a helmet I can give you a ride too.
They open around 7:00 am, you just need to sign the waver.

Correcto!

I'm not an engine builder but I can't imagine how you get to $30k on a 351w build. Even if you did/could I would think the expense would rise proportionately for an equivalent BB build. Apples to apples.

Bruce, don't expect Al to be there. He's convinced himself there is no such thing as a quick revving BB that can cut a corner. It would rock his SB world, destroy every hypothetical argument in his arsenal and leave him with a never ending desire to drop some real muscle in his car which of course he would never be able to let any of us know about and likey disguise by putting small block badging on his car and locking his bonnet shut.

Hook now baited with prime rib.

Al, in actuality I think a JBL with an aluminum 427 would make for quite a weapon and a real trick bit of kit. I do recall in my readings over the years that CS did want the 427 to have a longer wheelbase but AC used shorter tubing on hand. I'll have to find the article. Could swear I read it somewhere. How true it is not sure. Then again that was back in my Excalibur days so maybe it was a subliminal thing.

It's very easy... a SBF built to Dirt Late Model spec starts at $42K... SBC $38.5K. Built to off road truck spec is $48K.

These are open competition motors, meaning no rules or restictions other than single 4 barrel carb... any cid (BB or SB), any head, crank, rod (Titanium), compression, etc. Though BB are allowed, none exist in this form of racing. All are SBF or SBC, typically displacing 430 cid while weighing 360 lbs. These are the engines that drive the development of the SBF and SBC.
