Re: Stock Eliminator secrets?

When we order pistons for the back-cut 5/64" rings, we specify the groove depth. When using the spacer/ring combo, Total Seal advises that they furnish the dimensions to the piston mfg. for the correct fit. We've seen several cases of bad dynamic ring seal caused by poor fitting spacers/rings in st...

Re: 360 SBC Build?

Mark, I know you could make the camel hump heads work but it worth the time do them over when you would make power with some Vortec heads or aftermarkets.

Re: 70’s-80’s era low rise single plane intakes

Back in the 70's we used to run the Torkers and Tarantula intakes all the time with good results, just wished I would have known how to port them back then. Most of the other single plane intakes except for the Offy's single planes were just garbage. One time I ran a Eddy C4B and it was on a bone st...

Re: 360 SBC Build?

I have a 360 inch SBC short block I built a while back, I used a Mahle flattop piston with two small valve reliefs, a circle track piston I believe, I worry about piston to valve clearance with a 260 @ .050 cam SFT. I thought about building this with a set of ported 062 Vortec heads and a air gap i...

Re: Epoxy For Blocks

Here is what i used on a 409 block with cracked water jackets. I welded it with muggy weld and put AB epoxy over it. Let it set up and pressure tested the block on both sides for over 30 minutes at 40psi. No leaks, so I am happy with the repair. WTH is Muggy? It's a arc welding rod that is for cast...

Re: Budget 385sbc upgrades...too much compression?

With a 114° LCA you will be fine with pump gas and don't run more that 31 degrees total timing with the Vortec's that where they make the best power. If your cam was a 106° LCA than you might have some problems.

Re: speedmaster/ procomp valves

My new peanut port heads have Fererra valves in them and I was quite impressed with them. Will use again as valves on anything that runs high RPM is not a place to skimp on.

Re: Ignition timing after porting

I can tell you one thing for sure. After I took the Strip Dominator intake off my 461 that I used the burr finish on inc. the heads it had the cleanest runners and plenum of any intake and head ports I have ever used for running a couple of races. No fuel drop out anyplace even with the carb being a...

Ask yourself this, would you want to trust a nice engine to some china valves?

Re: Ignition timing after porting

The only set of heads I had to set the timing lower on were on 2nd set of Vortec's as they worked the best with 29-31° timing. The stock set I used ran from 34 to 36° but the 2nd set had some chamber mods that may have helped make some more power with less timing.

Re: camel hump vs vortec

I ran 10.90's@120mph with minimal porting and stock size valves with my 062 Vortec heads. Like to see that with a camel hump head. What track did you run at? What weight did you run at? Track is at 898ft. car with the SB was I think around 3250 without me in it, I am 180lbs. Have not weighed it in ...
