So just what is it about your 318 combo that you feel isn't fair?

I never said there was anything unfair about my combo, but there are combos who can't find any replacement blocks such as you

If someone building a combo is so concerned about the lack of availability of an aftermarket block, then he should build a different combo and buy the block of choice. I always say, the planning is the hardest part.

Really, you are willing to eliminate that many combos.

But I'm not complaining about not having a replacement block. I'm complaining about combos that are being given aluminum aftermarket intake manifolds in Stock!

David, you apparently don't know many hardcore Stock Eliminator racers.

And you want to limit it to that one subject.

Like I said in the previous post, that is the reason why people fill their blocks.
Others sleeve them.
A properly filled or sleeved block, machined with the right equipment and by someone that knows what they are doing, will make power.

I would be concerned if that 68-71 318 piston with valve reliefs is legal or not. That's a **** load of HP right there that no aftermarket block or head will make up for. Just my 2 cents.

I'm all for aftermarket heads. If Everyone Can Have Them!
Main benefit of a aftermarket block is take the hone better last longer but is heaver
You have aftermarket block and sleved it? Really
Reinventing the wheel ?

And I have heard that aftermarket blocks get a hell a lot more hp than 5.

David, it would be a good idea to fill them also. A stock 340 typically has about a .100" thick wall and if you run it as a .060" 318, you'll have approx .135" which won't break but it won't make great power either. A lot of aftermarket blocks have about .300" walls.
