Important if you run D-H/S or SA

You've never asked me the question directly. I'll give you my take on it. I build my own engines for better or worse. My performance level with my car is respectable. I have a production block in my car that has been honed 3 times and holds a pretty round cylinder. I have good ring seal and a pretty sound reworked oiling system to keep from running over my main and rod bearings going down the track at the RPM I run it at.

I have a new aftermarket block that is being machined to replace my block. For the most part it will have all the same parts in it as the engine I run now. Same heads and intake that I run will go on this new piece. I would be very suprised if it's 5 Hp better. It should stay round all the time from first hone on. One of the draw backs is its 46 pounds heavier than my stock block. Now the car has to be changed around to offset that. When I run it I'll tell you how much it's better than the stock block. If I had my choice, I'd take the better heads and intake any day.

No tap dancing here. Does that satisfy your question from the Pontiac end? BTW do you build any engines or even race stock.

I don't blame anyone who races that combo, especially Tom,Jerry, or Steve. They did the homework, the r&d and put it into action. They are all hard workers and stand up guys. It's up to us as their competition to try and keep up.

I am building a 67/68 cuda right now and to answer your question I bought two 340 dealer replacement blocks and have them sleeved down to a 318 bore. I plan on doing my own short block and have shane studley do my heads.

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