no, the 307 exhaust, well the diesel one comes in 4 parts
Pontiac didn't make a 307. If it's an Olds 307, you need an adapter or a BOP transmission.
Is it an Olds engine? Olds never made a 305. Olds did produce a 307. However, once the Olds V8 went out of production, Chevy 305's were used instead of the Olds 307. If it's the Chevy engine, it will bolt right in with no modifications. If it's the Olds engine, you CAN put it in a Camaro, but you'll need an adapter plate for the bellhousing. Chances are the exhaust manifolds won't line up with the existing exhaust either, not to mention a bunch of other little tweaks that you will need to do to get the Olds engine in the Camaro, but yes, it's absolutely doable.
You will need to remove the exhaust manifold retaining bolts in your 1993 Chevy Astro. Remove the exhaust manifold. Remove the exhaust manifold gasket and clean the surface. Reverse the process to install the new exhaust manifold gasket.
There is basically no difference. 305 is a Chevy engine and the 307 is a Cadillac engine. They are both the same and assembled by same company Well, on the other hand, it depends on how you look at it. The 305 Chevy is a 265 stroked with a 350 crank. The 307 Chevy is a 283 stroked with a 327 crank. In theory, the 305 should produce it's best torque at a lower rpm than the 307. However, the 307 should be able to rev higher and produce a higher peak horsepower. Kinda depends on what you need it for. There is also a 307 produced by Oldsmobile that is a V8 engine. It shares no other commonalities with a small block Chevy.
Yes, the exhaust manifold on a 99 Chevy S10 2.2 will need to be be removed during the blown head gasket repair.
It has the same bolt pattern and it will bolt up but you will need the correct flexplate.
Yes.
NO
no I respectfully disagree. I am running 305 Chevy TBI heads on my 1971 Chevy 307 and all is very well.
Quite a bit. Just with every engine brand swap, you are looking at engine mounts and frame mounts. The exhaust will not hook up one to the other. The Olds tranny will not bolt to the Chevy. The 307 didn't use a particularly large radiator, so a good 3 core for a decently built 350 would be minimum.
A 307 is a 283 with a 327 crank. You can look up specific dimensions at mortec.com
