Re: Shortening valve springs

Is a different set of valve locks or machining the spring seats not an option?

Indexing spark plugs

I’ve been reading through a bunch of my old late 70’s-mid 80’s car magazines lately, which got me wondering... Apparently back then indexing plugs was a BFD, as there was multiple articles on the subject as well as it was pointed out in the write up of many featured cars. Nowadays you don’t really h...

Re: From a 300-36 intake to a Victor Jr.

If I wasn’t 10 hours away now that thing would already be running :D

Maybe this fall I’ll make a trip up there. My motivation right now is inversely proportional to the temps outside...and it is just nasty hot and humid in Texas right now!

You didn’t give me any wheel studs that I can remember.

Paul, do you realize it’s been about 14 years since I helped you install the trans in that Camaro? You’ve got to work faster buddy :wink:

Re: A Victor vs a 300-36

I’ve never used a Victor before, but I have done back to back testing of a 300-36 vs a 7530 Weiand on a 250@.050 solid lifter 388 sbc. No comparison above 4500 rpms...the 300-36 was no doubt better at lower rpms, but above that, the 7530 just ran off and left it. If you are only concerned with power...

That is a beautiful torque curve! I bet it’s a rocket in such a light car.

Re: Straight through mufflers

I would imagine that would get highly annoying very quickly if you drive it much. One thing that would probably help though would be pointing the exhaust straight out the back, with the tip sticking out just a bit. I’ve noticed on mine, even with the really loud mufflers, that pointing the turn down...

Re: Straight through mufflers

A question to the original poster: Which one of these arrangements best approximates your exhaust? I'm guessing (a) dual v8 - no bank to bank mixing? https://www.speed-talk.com/forum/viewtopic.php?f=1&t=49628&start=15#p662181 https://www.speed-talk.com/forum/download/file.php?id=14132&mode=view htt...

Travis,yes,I have them on a 63 421 Tempest right now.Had them on my 455 69 bird and pulled them to try the 14in Superturbo.Hated the 14s,tried the 18 ST and hate them.Going to put the HPs back on.My 428 RA V in the bird has developed a bad drone at 2000 and have been fighting it.Only real change on...

Have you tried the Hushpowers?I have used a couple sets and really like them.Even better than the 14in super turbos.Tom
Are you referring to the Flowmaster HP2’s? I’ve never tried them, or even heard them on anything that I know of.

Re: Straight through mufflers

Does the exhaust have a balance pipe or X-pipe connecting the two banks? That sometimes help get rid of the drone at freeway speeds. No crossover of any kind, but also no drone at all with any of the mufflers. The straight throughs are just ridiculously loud...they sound really good at idle and low...

Re: Straight through mufflers

The DynoMax Super Turbos are my choice. Flow better than Flow Masters and attenuate the sound so they don't get you tickets nor drive you nuts on road trips. If you really have to have a noisy exhaust, try electrically controlled cut outs. Either straight to open dumps or diverted through glass pac...

Straight through mufflers

Does case size and shape effect the sound level of straight through mufflers? For example...all 2.5” straight through perforated core mufflers...3.5” or 4” diameter glass packs, vs something like a 6” or 7” round case dynomax ultra flow, vs an oval cased magnaflow? I’ve been testing some mufflers on...

Re: The funk...

I put a gallon of the fuel I pulled from the tank into a clear plastic jug and let it sit overnight. There is definitely water in there...and a serious amount of crud. The inside of the tank looks like it was used for salt water storage for a long time...it’s junk. So...I’ve ordered a new tank, and ...
