Re: 1962 Pontiac SD 421 # 127 heads

What could you see a 127 casting producing for flow in stock eliminator trim? The 385 H.P. rating isn't a gift but it's not horrible. Also, it's nice that the light weight pieces aren't mandated. Finally, 'Manual Trans Only' is not noted. ;) At 3,828 in 'D' and 4,020 in 'E' it would be a cool bruis...

Re: 1962 Pontiac SD 421 # 127 heads

The 1st SD 421's used 389 heads and put larger valves in them. I am guessing numbers 543797 for 1963 casting,and 538177 for 61-62. :Are you sure the number is 127? There were two heads that came on the '62 421 S.D. engines: -The early 540306 heads use a 1.92" intake/1.66" exhaust valve. -The later ...

I did find Torq-Thrust IIs in those sizes for ~$100 each.
I thought you were looking for something light weight? If not, there's tons of wheels out there that will work in that price range....Jegs cast knock off versions of the Welds, for example.

One single manufacturer deciding to double the price of everything they make is what seems odd.
It's not just Weld....all race wheels have increased in price. Weld held the line on pricing for many years.

What sizes/back spacing/bolt circle are you looking for?

Re: Weld Draglite/Prostar

If you mean the days of ordinary people buying Weld wheels are over, then I guess you're right. Take a look at the Race Star wheels. Their 92 series wheels are pretty nice....a pal has a set and I was impressed with them. If you have an NHRA or IHRA permanent number, Jegs and Summit offer additiona...

Man, I know it's been a long time since I bought wheels for anything, but holy hell. These things were always the default, affordable go-fast wheels at around $100 each. Now they're more than double at $225-$250. What happened?!
Those days are long gone...... :(

SBC adjustable push rod guide plates

For anyone that needs adjustable push rod guide plates, give the Jomar units a try. They are well designed and actually stay ](*,) where you position them when torquing the stud! No more cutting, welding, pasting, marking, or holding your tongue just right to set them up. I started using them a coup...

Re: .120 wall pushrods

I will sometimes use a 5/16 x .105" pushrod from Trend in applications where valve spring force does not exceed 600 lbs.Especially when "fitment space" is an issue. Walter, I've used several sets of those with excellent results. On a related note, I recently switched a set of those out for Trends 3...

Ball hone, clean the beejeezus out of the cylinders, make sure there's a decent amount of chamfer on the top and put a moly top ring set in it.

Interesting, never knew J.B. made this version. Have you ever used it to seal against the pressure and heat of combustion? Anyone who has used Belzona 1511 (Super HT-Metal) with this type of a issue? https://www.belzona.com/en/products/1000/1511.aspx Yes, I've used it....worked great. I haven't use...

Re: Cylinder Head Deck Repair

The question is there any type of high-temp epoxy or another type of a compound that could be used to fill it and also seal against the pressure of combustion and stand up to racing use?? J.B. Weld 'High Heat' is what you're looking for. Make sure there are no raised edges along the scratch. If so,...

Re: Valve springs

We don't back the valves off on any of our drag race stuff in the off season...no issues at all. In fact, given the 'dry' characteristics of some of the race fuels (C11, C12), frequently rotating the engine to stay ahead of any sticky guide issues is a plus.

It's a simple hydraulic system. Not uncontrolled leaks. That's crazy to claim that.
Uhhh.....the word "uncontrolled" was not in anything I wrote.
