In 1987 the small block Chevy was revised for your '91 you need what is known as a "vortec" intake the head mating surfaces are milled at a different angle, and it has 4 bolts per side holding it down vs. 6 on the pre-'87 engines.
On a non-TBI engine, Yes.
No, 283 has too small a bore. The old power pack heads that came on some 283's were 202,160's, so I would think the 305 heads should work just fine. Not sure about the resulting compression ratio though. The 305 intake might be aluminum, which would be lighter than the 283 intake.
intake manifold is DIFFERENT for models 1985 and 1988
The connector into the intake manifold of a GM 305 and 350 has been known to be quite fragile. If the connector has broken you have little choice but to replace the manifold.
It will as long as the 305 is a VORTEC ENGINE TOO.
Yes, a 283 exhaust manifold can fit a 305 engine, as both are part of the small-block Chevy family. However, there may be minor differences in bolt patterns or exhaust port shapes, so it's essential to check compatibility. Additionally, using the 283 manifold on a 305 may affect performance due to different flow characteristics. Always verify fitment and consider modifications if necessary.
Yes it did.
PROPER TIMIMNG SHOULD BE LISTED ON THE INTAKE MANIFOLD PROPER TIMIMNG SHOULD BE LISTED ON THE INTAKE MANIFOLD PROPER TIMIMNG SHOULD BE LISTED ON THE INTAKE MANIFOLD
No. There were major engine changes between those years.
It is an intake off of a late sixtys small mblock chevy. 350cid or 305 cid
yes
take all the wiring and hoses loose from the top of the engine, and you might have to remove the valve covers. then just loosen the intake manifold bolts
