Tell me something,,,,,

   OK,,on the 1982 Silverado C10 I bought a couple of weeks ago,,,,Yes Shameless,,I bought a Chevy to stay in your good graces,,,,, I finally got to where I was wantin to put a spark in the engine to see what the miss is, so I put some new spark plugs and fired it up,,it ran but was very rough as it gots the quadrajet carb with bout 5 1/2 miles of vac hoses,,and most of them had been plugged by the PO, so,,I removed all that chit and throwed thet carb in the cawnor and was just lucky to have an adapter for a Holley/ AFB to a quadrajet,so I installed the AFB and fired engine up again. Still had the little miss and engine would "pop" out the carb when tryin to rev engine up,,,would do it every time in reving up. Thinkin engine might have a burned valve or worse,,I pulled the new plugs and ran a compression check and all the cylinders had from 100# to 115# compression,,,WTH,,,?? I just knew there would be one cylinder with low numbers but these numbers, while not the best, are very good for this old a trk,,,, Anybody got a clue,,,????

probably the 1983 gas still in the tank.....

OK,... did you replace  ALL the fuel filters ?

mileage reading ??

I ant no mehanic   but have fought a Chevy or 3. In the wonderful days when those trucks were current,perfect if you ask mister "pretty". The very fragile carbon wires,I think a bit tougher today. The plate in the disturber that gets cracks,and then the cam that gets flat.  All of that works they run unless they are shenaigaining you,  which has been known to happen. 

 If my remember, is not telling me wrong,the cam could go from ok to  bad real quick.

   Chit,,Thad,,after re-reading my last post,,,even I can't really understand WTF I want to do,,,,,, Yeah, the dude did tell me I would have to "wallow out" some of the bolt holes on  MY manifold in order to work on the TBI heads/block,,,then something else bout the distributor,,then will have to modify the ECM and,,,and,,,chit,too danged complicated,,believe I'll pass on thet 350. Gonna pull the 305 and tear it down see if it fixable and still keep lookin for a 327 or a 350,,, 

Anyway, my 305 does have a block mounted fuel pump,,,,,,

That cam can get real bad real fast. My dad and his best buddy liked going to the livestock auction a 100 miles away. Nether liked wrenches and all that grease and oil. They liked  horse and cow poo much better. They had 2 or more trucks to pick to drive, and I think they had a cow or 10 in a trailer. So not being tuned in to mechanics they may have missed the signs, but made it to sale and on the way home they couldn't go any futher. A new cam in the O'l 350 and that truck went a lot more miles.

I know the rest of the world is not so regulated, but here putting a different engine size in than the factory used causes all manor of paper work head acks. And I know part of it has to with the feds that I think could even happen in your part of the world.

Oh the friend down the road that does engine machine work also told me 7 psi in chevy was all you needed for oil pressure. Claimed race guys liked it low to not be wasting power they could use for other purposes. An the one of a kind of stuff is what he liked,cause he liked to do oddball stuff. So lots of work for race car guys as well as the Baja off road guys. Also just learned the old Caterpillar oil pressure gauges that didn't have any numbers the normal was 7 to 20 psi.
