selling a 283 4 bolt main

 

nope,not oem anyway

 

Never say never . There are some 327 SJ 4 bolt mains used in combines.

 

with this block?

3914636....307.....68....2

yeah...right....

 

I didn't look at the link, just FYI.

 

Oh, sorry, I was being snotty at the guy who's auctioning the engine, not you!

 

not the 283, which is my favorite small block

 

Yeah, they discontinued the 4 bolt main 283 around the time the fuel injected 307 went into production.

 

Not on the overhead cam models. Those are still in production and the standard engine for the 2006 Z-28.

i'll bite, what's a sj?

 

small journal

 

welllllll,duhhhhh(as i'm beating my head against the wall)

 

I seem to remember Milodon making 4 bolt main conversion caps for Small journal small blocks.Probally not this particular motor but it could be done.

 

283s had 3-bolt mains and didn't use rod caps - the distributor was driven off of the water pump geardrive and all 283s used the underslung sump phenozzinator

i had one of those once. but it had babbit bearings. and dippers on the rods. i ran one of those 3/4 full race cams and a flood master carb. and yes a three on the tree baby!!!!! it ran like a sumbitch

 

P.S. i think the cam was a joey chitwood?????

 

I just looked at cars & parts chevy V8 engine casting numbers 1955-93 and it doesnt ever show a 283 4 bolt. The only time i have ever seen one it was after market and used splade caps. Im me with the numbers from the block and i will look them up the best i can if that helps. Jeff
