94 Gmc Engine Terms Questions =)

[Marsal420]

I was told that i should have my engine ....

( Ported and Polished ) now i dont know much about engines but what exactly would that do for it if i have it rebuilt and have that done to it? Would it give it any additional power?

Also i was told to have my engine's ( Bore increased ?) also another term that i dont have a clue to what it means

And, finally what exactly would a ( Stroke Increase ) do for my engine.

I know you all may laugh at me but i dont know what any of this means because i was never tought any of these terms nor meanings.

" I guess that is what i get when i was brought up in a household surrounded by Mechanical Idiots "




" Please Help

What engine in what vehicle, porting and polishing increases air flow thru the heads, boring is increasing the size of the pistons in the cylinders and stroking increases the distance the piston goes up and down in the bore, simple terms here, google any of these for more definitive info.

All of these mods are expensive and require engine removal/disassembly, not really practical on a limited budget, more like wishful thinking/fun ideas. A 383 stroker motor from GM would be more practical.

GM Goodwrench carries crate engines which (I believe) are available through your dealership. Here is their website:

Cost-wise, you would probably be ahead by just having the existing engine rebuilt unless you have a cracked block or something more significant than normal wear. Give a Chevy dealer a call, they can probably run through some options and costs for a rebuild versus and engine swap.
