Glensgages, I've read some pretty nasty stories about vacuum problems running too high a cam. Have you noticed anything like that with the 292H? This is a daily runner, fun car, it may go the track once or twice but that's about it and am trying to avoid costly upgrades with vacuum additions etc.

Jack and Glensgages, thanks gents. I figured out what my problem was with my spread sheet..........operator error!!!!!!!! I was putting in dished as a negative volume, WRONG. Anyway now my spread sheet matches your numbers, Jack, exactly. So that now determines a flat top -4cc 2 VR's piston, 400...

Jack, thanks for the info about the gasket sounds like a plan.:D Looking at the stock 350, and using a 3.48 stroke, 5.7 rod and 9.025 deck, you come out to 1.585 CH. I'm now making the assumption that the OE piston was a 9.5 domed as that gets you really close to the 8.2:1 CR with a 76cc...

Yea this seems to be the problem that I've run into...........I can't get anything solid to work from. I've plugged various values into this and keep coming up short ( higher compression than advertised), the numbers ( I made my own calculator) never seem to be 8.2:1 unless I make drastic...

I am trying to figure out how the compression ratio of the stock 350 in the 81 vette is rated or specd at 8.2:1???? I came out with a 8.9:1 compression ratio, something is wrong..........obviously....... with the info I used, so I'm looking for the "right" stuff, so to speak. The info that I...

Hey Jack, thanks for the info.............the more the merrier. I just read an article that said Chevy got it right when they designed the 350 5.7 rod and stock stroke in that it is less than 18 degree angle when the rod/piston is 90 BTDC. Apparently this was a problem in larger blocks say 400+...

OK gents got more info about this. I talked to a master engine designer as Delphi yesterday about this 383 conversion. the scoop: Leave the original rods(5.7"), use new rod bolts ARP, DON"T use 400 rods. Light weight pistons from SRP, ROSS or Linata, flat top aluminum, stay away from...

Corvette cntral had them, chromed, thanks for the link, $1249.

Hey redman, I'm looking into converting my 350 into a 383 stroker and gathering info. I am in need of counsel as to WHAT I need to accomplish this. I would be very interested in buying from this guy IF I knew what I needed to begin with. I'm looking to push about 400 HP, don't know what cam...

I'm looking for a particular set of rims for my vette. I see them all over the pages but for the life of me can't find a picture of them to post to ask. One of the mods "78silvanniv" has them....slotted, I believe stock '81 wheels. the ones on his are aluminum.........I'm looking for a...

There are a couple of stroker upgrade kits on Ebay for around $600, anyone know if these kits are good or questionable??

You've got a bad relay, it's not engaging with the brake pedal or turn lever, both activate the same relay, easy to change. Cheers.

After reading all the other reports on this............it does not look like fun AT ALL!!!!!!! It would be nice if it was a hose..................can you spell M-U-R-P-H-Y....my luck it'll be WAY worse. I'm getting info on a stroker rebuild and am now toying with just taking the whole thing out...

Gents, thanks for the info, I'll peruse your sites and continue gathering info. To answer some of the questions posed: The budget has no limit until the wife cracks down and realizes how much I'm spending!!! I'm figuring about 3-4K for the motor. I'd like to see it pushing 400+ HP when finished...

Last fall when I put my vette to bed for the winter, I noticed a puddle of fluid on the floor on the passenger side of the car. Upon further inspection, it was more of a lake than a puddle but too cold to do anything about it. I'm assuming the carpet is ruined etc, haven't had the heart to take...

Hi ladies and gents, new to the board and am looknig for some help and guidance. (No snide comments please, not THAT kind of guidance!) ha ha Anywho.....I am toying with the idea of moving up to a stroker. I have a major rear seal oil leak and I'm gonna have to pull the motor to fix it. So...
