Yes it was an 1 gen Chevy sb. I personally don't like LS engines, they seems to end up more expensive than a 1 gen sbc and are full of electronics, for the quarter mile the old sbc and bbc always seems like a more competitive alternative then LS.

Is R-block the same as X-block? Is those blocks still in production, if so where can I find one? I will be going white stock block for now to get the setup right and then I can invest in a good short block, but it is good to know what is available. Btw is there any good books about Mopar...

If you change any gaskets remember to fastening the bolts with a torque wrench as it will prevent mosts leaks regardless if it is valve covers, front cover or oil pan. I Just wanted to make it clear, it really helps.

It can't be from the valve cover breathers? But you explanation is probably more likely.

maybe a engine crank main seal? Or the oil pan? A tips when mounting the pan is to fastening the bolts with a torque wrench in a cross patten. But the oil leak can come from many places, dip stick? front cover? camshaft seal? valve cove? its hard to tell. But i don't think it is any danger, it...

It was a 2 bolt block in that corvette. However it hard forged piston stock, but in the end it throw a connection rod and it took with him the whole bottom part. It did 765hp and 977foot-pounds with a much smaller turbocharger and did 10.862/134mph at 1/4mile. But he did not dyno it after the...

Hi I am new at Mopar and wonder how much power for example a 318 will hold up to. Is the 318/5.2 magnum stronger then the LA 318? I was going to build a 500-600 hp when I read that original blocks do not hold up to on much more, but I wonder if this is really true as it seems a bit...
