I agree with 66 fairlane. Way more comfortable with out using carb plate

Thanks Blair sorry if I put you in a weird situation. Realized after I posted but to late then. Like arguing with the wife and your words slip out and you want to take them back. “BUT”
So there is really 9 ways to go. There’s too much info to remember without seeing it laid out I don’t care who you are. Ok much better. So what happens to the B and F head to make if for the larger bores on the bottom of list. And I would assume they come in different CCs.
Another question do some of these make more torque than the others do they all have the same intake runners CC wise I guess besides the porting.

I picked up on that Rory. But realized he was talking about preload. That’s why I said 1/2 turn. I think he was going to far and effecting the idle. When he gets back maybe he with explain better

By looks at least I could be wrong but is that piston heavy? Also looks like thick ring set.
Sorry missed the box picture. That is a heavy piston. What is the benefit of the weird design.

I understand but I wasn’t talking about a stock crank. I thought when scat makes them you can get them as a steel crank and they were the same 2.20 journals as the 4.250 cranks. That being said I understand what you are saying.

When you got off the subject with the 400 inch boost motor a lot of guys around here are running blow through carbs with procharger. My buddy a few houses down (Chevy 540) makes 638 naturally aspirated with 600 lbs torque with procharger he makes 1070 Hp and 1247 lbs of torque. Makes me want one maybe next setup.

I think probably almost 200 horse more than he had. She’s gonna scoot.

Was looking at those cylinder heads Blair with a 280 cross volume do you need to be speeding or filling those runners.

If the fuel systems up to it I believe you just have to fatten up the jets
