From the looks of  that mag you better have your pistons coated or it might burn holes in them :-D

HAHA!

Roy Dilley finished the aluminum intake!

Nice looking blower manifold. Just curious why you did not put a burst panel on it, instead of two pop offs? Maybe not enough room?

well, I guess because I thought it would be sufficient. Did I go the wrong route?

Burst panel may be a more reliable way of saving the manifold. You know it will burst and not get stuck. But it sure is easy to pop one with a little backfire when starting. Which is kind of a pain also.

When I was deciding on a pop-off vs burst panel, I looked at SBC blower intakes. A lot of the street ones used the pop-off. Even if we hit our HP goals, this will only be equal HP wise to a mild to mid SBC. I thought this was a good way to go, but I've been wrong before!

Good thing is, that if I end up needing to change it out, I still have time, but I think it will work.

Buddy, I ran a blown big block Chevrolet for quite a few years drag racing. Also about 3 years on the salt using a manifold that had a pop off valve, never had a problem. We also use a home made pop vlave on the straight eight Buick #1950 with no problems.

Sparky- we're going with special made, coated, blower pistons.

Thanks for the info guys!

Ok, we're still moving along, but it's not all that exciting!

Body is completely disassembled, and blasted. It and all the parts are getting epoxy primed, and then we'll start the body goof-off and rust repair.

We are going to get the frame epoxy coated in a shiny black, then put the body back on it, after the body is primed. We will then give it it's initial body chop. We'll just tack the top on, so that it can be removed, to weld the roll cage better.

The car will then go to GH, who is doing the roll cage. I feel extremely lucky to have someone with Gary's experience doing the cage, as I know it will be done right in regards to safety, and tech specs.

If I were welding the cage I'd be really unhappy if you epoxy coated the frame first, as a matter of fact I might even say no thanks. The fumes that come off the paint are truly noxious.

Why not cut out the floor such that the body can be slipped over the cage and then the floor welded back in. That way the cage could be easily fabricated and then painted at the same time as the frame. The body could then be installed after the painting is done. You'll get a much better job. Just my humble opinion gained through some painful experiences. :-D :-D :-D

Um, yea,...um, that's what I meant!

That's a good idea. I guess in trying to plan all this, and get so much done in a limited time, I didn't think about the coating and fumes.

Thanks a lot!

I chatted with GH, and we'll leave the areas on the frame that need to be welded on uncoated.Thanks again Peter Jack!

...and the saga continues!

We're working on the bellypan, so that we can run /BVGCC. Obviously, we'll have to make some mods to it, but we have it 'roughed' in.

I forgot to ask...

I'd like to weld the nuts on top, and run counter-sunk bolts from the bottom, so that the heads are flush with the bellypan.

Will this be acceptable with tech? If not, anyone have a good solution?

Boring stuff, but necessary . We don't want the body to rust, now that it's blasted, so we coated it
an epoxy sealer primer.


Still need to know---- :?      I'd like to weld the nuts on top, and run counter-sunk bolts from the bottom, so that the heads are flush with the bellypan.

I'm not tech but I sure can't see any reason it wouldn't be OK.
