82 cross-fire engine rebuild
I bought this coll. with 72,000 HARD miles a couple of years ago, and Iam finally getting around to do some serious work on it. I was wondering if there is anything "special" I should know during the rebuild of the engine and if there is a simple way to gain some HP. Right now the engine smokes on start up when sitting awhile, and Iknow those are probably the vavle seals. But, doing a full restore I would like to go ahead and do the whole engine. Any suggestions??????

The easy way is to replace your missfire intake setup with an aftermarket carb and manifold or real fuel injection, xe292 cam, alluminum heads, headers with true duals, no cats, no emisiion controls, 355 gears, 5 or 6 speed tranny, centrifugal supercharger and lots of stickers, even if you dont have the stuff :lol:

Re: 82 cross-fire engine rebuild (purdyvette)
If you want to keep your x-fire setup, i believe there is a manifold out there that showed up on the forum about a month ago that is compatible with the dual tbi setup and will allow for much more power. do a search and you should find it i bet. If you dont want to go too crazy with the rebuild, get this intake, a new set of heads, a reasonable cam, a higher flowing cat and you should see a nice jump in power.

Get some real advise, rather than those that call it "missfire" yet have no clue what they are talking about.

You might wanna try the CROSS-FIRE FORUM; sections are dedicated to intake, engine mods, exhaust, fuel system, etc. An alternative to the stock intake is found at: http://www.X-Ram.com Might wanna look into that, too.....

Re: 82 cross-fire engine rebuild (Desertdawg)
I don't think gameshow bob means the X-ram, I think he means the SY-1, which IS a crossra. The X-ram is not.
The SY-1 is an old smokey yunick manifold with funnel shaped runners that almost devides left & right bank. It was used on 302 engines that revved pretty high (I think above 6500). There's a guy on the site that dawg mentioned that makes the lids needed to adapt your TB's to that manifold (Lionsden is his name). All you need is a small HEI w/ external coil and that manifold (discontinued but they pop up on ebay frequently)
The same guy also bores and sleeves the throttle bodies.
