Ritter 59 degree iron block

rrvolare said

My original goal was 600 -650 out of a sb ...and as much tq as possible .... but since the factory smallBLOCK may not be able to handle those kind of numbers ... and street manners being poor... i had no choice but to look to a BB... the HP and TQ i was shooting for from a factory BB was around 650 HP and near 700 TQ with good street manners being more reliable ....never was aiming for 800 HP... i guess i should of used a range of 600-700 out of a factory bb ?

If your tune up is good, and you keep engine speed reliable under 7k you can do 600 HP on a small block. Much more than that and your pushing it.

That means a cooling system that is overkill, main studs, a block fill, a crank with center counterweights, as light a bob weight as you can get, an liking system capable of dealing with the power level you want, including a crank scraper, a damper that don't have rubber bands in it, unless you can afford the R&D to sort out your bob weight, RPM, stroke length etc, and ATI won't do it for me.

Use an engine plate at minimum, don't tie the engine down with the OE mounts and a mid plate would help like hell.

I can say the exact same things are required to build a big block anything with the power levels you want, with a stock block. It don't matter what name is on the valve cover.
