Engine rebuild or new Long Block
Ive been talking to shops in my area about rebuilding my engine. they say it will cost anywhere between $1500 and $3000. A long block would cost me around $1500. I already have an RPM Air Gap manifold, headers, a 750 cfm edelbrock carb., new belts, new spark plugs, new Spark plug wires, new HEI distributor cap and rotor, and MSD ignition, and a good starter.
My question is, would it be better for me to go with just buying a new or reman. long block instead of getting my engine rebuilt?

Also, would it be better to have the long block installed by a pro with the better tools and engine crane? I'm on a very tight budget, infact I have to apply for a credit card to get the money (my credit is great so it shouldnt be a problem).

In most cases I would suggest building it yourself. If your referring to a small block chevy they are a breeze to rebuild. But In this case being you want to stay in the budget then I would suggest getting a crate engine from GM. They have several engines with several horsepower levels at a good price plus they are backed by a warrenty. I`ve seen some get remanned engines from Advance auto, Autozone and the like, seen many have issues and had to start all over again. One friend of mine installed the engine and ran it about a month, it ran hot on him and the block cracked in the number 7 cylinder from top to almost the bottom. Also heard of horror stories concerning other remanned engine companies so it makes the GM engine look better as it eliminates alot of hassle, once you buy it from a parts store chain, they don`t want to see it come back and will give you a hard time asking you 20 questions trying to lay the fault on you. They do this on common parts like starters and etc. so they really give you the drill on a engine. With the GM engine your getting what you pay for, with the parts store chain engines, your not getting much, as the companies that reman them put "rebuilder" pistons that have .020 off the compression height which kills compression, quench and power. The engine will be a slug and drink gas.

Thanks, I am looking at the summit catologue right now and the gm engines are probably the best way to go after what you say, and it makes sense to put a GM motor in my Chevy el camino. One thing that I am worried about is getting one with over 370 horsepower and ruining my transmission. I dont know the strength or condition of my TH350.

most th350s are VERY simple to rebuild, and will stand up to about anything thrown at them.

i think your thinking of a th400 its much stronger than a th350.
