Technical If you found a cheap 305 SBC....

Thanks!

 

If it’s as advertised ya did good

 

If that's correct, the heads should be centerbolt.

The heads appear to be '80-'85 ones. Roughly the same combustion chamber size as what is "supposed" to be on that block.

 

There is one page I found that does not show 416 heads for that block number. At least it's a whole 305.

 

It should be fine, barring any wear/damage.

I'd run it.

 

Back in the 80's those 305 HO Monte SS's where the cats ass and dam near indestructible! It will get you from stoplight to stoplight just fine. Larry

 

UPDATE: The warm weather is finally here, and so this is what the $241 305 looks like now. It will be mated to the 700R4, and be in the frame of the '29 Stude this weekend.

 

Little bit more that $241 into it now

 

Yeah, but when you start with a rebuilt long block for that much, this will still be the cheapest engine I ever put together!

 

I love 305 motors, never paid more than 50 for one and often find I can buy the 700r4 trans behind it for another 50.

 

I had a pretty good running 305 in a mud truck when I was still in Mexico. Granted it was not stock but it pulled the old Silverado just fine I was happy with it.

Now to the question at hand, I may be suspect of a 350 dollar rebuilt 305 short block. That is pretty close to a set of gaskets and a paint job. I would look in the cylinders at the very least, if there is a ridge and no hatch marks in the cylinders I would guess that you are actually looking at just that a set of gaskets and a paint job.

The heads now are a different story. if you can verify that the heads have had a valve job I may use the heads. You can find good heads all the time in the 100-150 range.

 

I'd say equipt the same each will produce about the same hp.

 

Today it went into the '29 Stude chassis. The trans. will be painted orange to match.

 

looks good from here, Is the frame painted Cat Yellow or maybe I have spent to much time around that yellow. Cant tell the horse power from looking at it. Good luck

 

It's a shade of light brown actually. I had it powder coated, and wanted to find an uncommon color.

 

Hmmmmmmmmmmm...looks like a 283 to me!! (maybe a 327 if its 'cammed-up' enough!)

You DID cam the crap out of it didn't cha?! If it ain't grumpy...it ain't a hot rod!!!
PLEASE don't tell me it purrs like a..........Altima!!! This IS a 'hot' classic car UR building, right?!
Looks great

29 StudeDude,

Bought an '81 Chevy 1/2T pickup new that had the 305 with 4bbl auto w/ lockup conv.
It ran great and was really quite impressive powerwise. Had a cam go flat after a couple years, put in an RV cam and continued to be impressed with the 305.
Hope all goes as well with your combination.

 

We ran 305 sprint cars for a while. 550HP with a solid cam, RHS200 heads and flat top pistons. What's the problem? They react to bolt on stuff like any other engine does. Liked a roller cam and dry sump even more but that's a bit much for a street car.

It has a performance cam, but it was already installed, and the seller didn't have the specs. Thanks!

 

The rebuilt $260 700R4 I bought used with low miles has a lockup on it. I can't wait to see how it works with the performance cam. Thanks.
