so im super confused. i found some parts on competition products for a 383. well i just realized that the 1983 camaros 350 4 bolt was a 5.0 am i going to run into problems making this a 383? i mean after the clearancing and machining does it make it a 5.7? thanks for the help guys

 

With a 5.0, best you hope for is a 339 and you can't run 2.02 valves in the smaller bore.

Same thing as starting with a 350.....030 over & a 400 crank, turns a 305 into a 335.

Either buy a new engine/block to build, or be happy with 339.

I suggest getting a 350 block to start building from, if not a full 350 engine (to start building with).

 

rebuildable 350's are a dime a dozen, get a 350, enjoy the cubic inches.

 

If the engine you thought was a 350 and is really a 305, it's physically impossible to make a 383 from it. You can't bore the cylinders enough to get the same bore as a 350 block. As mentioned above, the best you can do is make it into a 335. Using a 350 core, you can spend the same amount of money it would take to make a 305 into a 335 as it would to make a 350 into a 383.

Start with a 305, spend money to increase a small bore engine to less than a 350 or spend the same amount to make a 350 even bigger.

 

thats exactly what i am going to do with mine... i have a 305 right now not happy with it at all. buying a 350 next month and going to turn it into a 383! go with the 383 you wont regret it

 

wow im glad i talked to u guys. so if i get this 83 camaro im after would i be able to lose the 305 and put a 350 in it? (obviously going to 383)

 

Externally, as far as motor mounts & the transmission bolt pattern, every SBC from a 265 to the 400, are the same dimensions and direct swaps.

You can drop in that 383 & tell the Rustang, he just got beat by a 305!

My old 78 Stepside truck had "A 350.....More or less." At least, thats what I always told everyone, yet my "350" only lost 2 races. And I already knew I was gonna lose one of those. I just wanted to see that car run.
