Re: Important if you run D-H/S or SA
 

Now you're going to have to explain just what it is that I'm tap dancing about. Aftermarket aluminum intakes on combos that didn't come with aftermarket aluminum intakes aren't stock and shouldn't be legal in Stock. That simple.
OBTW, I'm not much of a dancer.

|You are still tap dancing Billy, I have asked multiple times, how much hp can be prodiced by after market blocks or blocks never in other combos?

After market and performance blocks were never installed either. Or does this question, throw a real wrench into your complaint.

And I never said, you were a good dancer, a hell of a good racer but not a dancer

Re: Important if you run D-H/S or SA
 

I reenergized post but I've said very little since .
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.

Re: Important if you run D-H/S or SA
 

David, I hate to rain on your parade but if you have a cast iron block with 8 hardened steel sleeves in it then your deal is better than a cast iron aftermarket block.

I agree!!!!!!!!!! 10HP!!!!!!!!!!!!!!!!!

I'll take the heads and intake! Probably worth 60HP

Re: Important if you run D-H/S or SA
 

Well I'm about 60 short of Jerry so hopefully that new block will get me close. I hope Warren Johnson, or somebody of that caliber told you that. I should be in good shape then. Thanks for clearing that up. Good luck with your project

Re: Important if you run D-H/S or SA
 

So you are against all aftermarket heads too?

Re: Important if you run D-H/S or SA
 

Todd, All I want is an even playing field across the board. Nothing more

Re: Important if you run D-H/S or SA
 

For you 71 and later 340 guys there is a Thermoquad adapter in the direct connection catalog that should be easy to get approved. It's from Edlebrock too.
