upgrading my engine

So I have a 305 in my 87 Camaro now. I found a 1970's 350 2 bolt main block and heads for sale locally for $200. What do you guys think? I've been reading around the net that 2 bolt 350's aren't worth building. I also don't know if $200 is a good deal or not. The block and heads have been professionally cleaned and prepared for a project the guy was going to do but he claims he chose to go in a different direction. Opinions?

Re: upgrading my engine

Does it come with the rotating assembly?

See what the heads casting number is they may be boat anchors in waiting.

Re: upgrading my engine

How much are you planing to build up the motor? A 2 bolt main, is fine if your staying under 500ish horsepower I believe. You can also upgrade the main bolts to hold up to 600 horsepower.

Re: upgrading my engine

I'm not really wanting too much horsepower. My Camaro is my daily driver so it has to remain streetable. I was aiming for 300-400hp. I'm more concerned with the price. Is a 2 bolt main 350 block and heads worth $200 CAD? Also, the guy told me that he is selling just the block and heads, no cam, no pistons etc.

Re: upgrading my engine

I paid 100 for my block alone, but it had already been to the machine shop, dipped, with new cam bearings, and bored out. What are the head casting #'s?

Re: upgrading my engine

Does the block need to be bored? Either way, i'd say $200 is fair. I'd leave the heads on buddy's doorstop, and use your 305 heads. Chances are good that they are better anyway.
You'll need to buy a crank, pistons, etc. You'll be in $1000 when the smoke clears or thereabouts.
Everyone talks about a 4 bolt, but for a car, a 2 bolt is just fine. I have a 2 bolt, lots of people do.
Where are you in BC?

Re: upgrading my engine

I don't know what the head numbers are yet because I have been talking to the seller via email and he hasn't replied yet. I'm just wondering if going with a 2 bolt 350 is really worth it compared to building my 305. I'm in Victoria BC by the way.

Re: upgrading my engine

Yes, a 2 bolt 350 is a 350. Consider it identical to a 4 bolt 350, the difference is so slim.
Don't bother building the 305 if you can get a 350 that cheap.
