RPMing a SBC engine.

[lefty o]

How high should a 3.53" b x 3.00" s = 234.88"cubic inch engine rpm if built to do so?? 8, 9, 10,000 rpm and higher?

I have read and heard about guys rpming the little 265's and 283's way up there so just am asking about one made from the 267" engine block is all.

I'm thinking to just rpm it whenever I need to get out of somebody's way here is all.

Drop it down into 2nd gear and put my foot in it and let her go to way up top. Get outta the way, then shift up to 3rd and continue down the road.

you can spin the piss out of it, but it doesnt mean its gonna get out of its own way.

NASCAR 9-10 k-----Pro-Stock 10.5k-----Comp. Elim. 10-11k-----F-1 14k or more All spinning them up by choice. Like David Reher said , MORE explosions going down the track. If yo drop from 10,000 rpm's to 8,000-----in a 10 second pass you are going to loose a lot of power strokes

In any cid motor you need to make more hp at the flywheel end of the Crank then the amount of hp friction that gets generated on the other side of the Crank to reach a given rpm, period!

spinning the engine to the rpm is the easy part. Making HP up there is another thing entirely.

...A small very high RPM street V-8 would lost with a 4 speed manual unless geared to run at over 4500 rpm in most situations.We all know how much fun 4.88 gears are on the highway.....In the 1960's Honda motorcycle had 50-250cc multi cylinder 4 stroke race engines that reved to 20K rpm and some idled at 9000 rpm...Power came on at 16,000 RPM...

Yes Reed you are correct. EXCELLENT cylinder heads and ALL the other engine parts to help those cyl. heads perform to their best=making power at high RPM's, This equals money,money,money. Mark H.
