Re: Determining balancer size?

Buy a Powerbond 8" with a nodular iron or steel outer ring. This stuff isn't that complicated. Higher rpm or external balance is where the rules change. I have never had a problem with the GM stuff up to 7000 rpm.

Re: rear power valve on HP holley should i run one ?

I tried running a power valve secondary on an 4781 and it bogged terrible at the track. It didn't show up on the street because the tires were already spinning before I got to wot. I suspected the power valve took too long to open and feed fuel. It has to be sized correctly and jetting adjusted ,, ...

Re: Worst-case Header Sealing Scenario? What to do?

You might try the Remflex gaskets. They are thick graphite with a non metallic mesh. They will not tolerate over tightening, but will seal almost anything warped or whatever.http://catalog.remflex.com/

Re: Hyd Roller SBC bracket drag car

For the cost of the hydraulic roller equipment, you could likely turn the 350 into a 383. I'm with the suggestion of a T 350 trans, they are so cheap and easy to build.

Re: Rocker arm stud replacement

Actually, the 305 heads will go on one of the 350 engines. It gives them a nice compression kick, about a full compression point and an improvement in quench. I did just rebuild the 305 for my El Camino. It was getting mileage in the 19s and had all of the power I needed before the improvements I ma...

Re: Rocker arm stud replacement

The stud is on an end exhaust. The thread is stripped, so its likely that caused the problem. I have a hydraulic press and a drill press with a compound tilting table, so I can do a good job of it no matter which way I choose.

Re: Rocker arm stud replacement

Will a used stud from a junk head be ok if I lokctite it in? I guess my question was more about installation. This will be a stock application.

Rocker arm stud replacement

I have a set of stock 305 heads I was going to use and noticed one of the studs was chewed about 1/3 through. I haven't replace one of these since 1976 when I popped one out of the head on my L76 327. I have no idea what I did back then and have gotten wise enough< (as in old enough), to think there...

Re: How fast can a 400 sbc go?

Assuming you can get it to hook and it doesn't blow up, (stock block), low 11s easily, 10s with proper tuning. Much easier than trying to do it with a 350. Larger small blocks like big heads and a cam with lot's of lift, difficult with a flat tappet

Re: Stroking the 305 SBC

The only way that will work is if you cut down a stock 400 crank main journals. Then it would need to be balanced. Stock 305 pistons are terrible unless you have the stock flat tops. There are pistons made for using 5.7 rods with a 3.75 stroke, and there are rotating assemblies. I have yet to see an...
