500hp 350

[eel757]

I have a 350 sitting in garage just waiting for something to be done to it. is it reasoniable to try to make 500 to 600 hp and keep it half way streetable or should i just sell it and get an ls.

Probably would have bore and stroke it, increase compression, run a giant cam and rev really high. Not very streetable. Probably better to start with a bigger engine, but if it has to be a small block, you should consider forced induction. What will you use it for?

i plan on putting it in a monte carlo so i want something i can drive around town for ****s and gigs

If 600hp is your goal, start with as big of a foundation as you can afford.
600hp stock block can be done, but everything else would need to be replaced, and a decent amount of machine work to the block itself.

id be happy with 500 maybe a little less and some spray just don't know if its worth using the block i already have. i know I'm gunna have to get it machined could i reach 500 by stroking it into a 383? id like to be in the 11's in the 1/4 mile

500hp 383 is hard not to do... Just dont use junky heads. Even with vortecs you could get 500 ftlbs and 450ish horse power out of a 383 and still be streetable.


The real question now adays is why bother. Im almost done with a 550hp LS build, completely steetable, out of 330CI...

A 500 hp SBC means basically junking everything in the engine and replacing it with aftermarket parts. Boring and stroking increases the power potential. The old saying is speed costs money, how fast do you want to go? 350's aren't exactly rare or expensive, so having one on hand doesn't really net you much in terms of existing capital investment.

Unless you have some special need or reason to use the 350, you're better off going with a big block or LS. Those motors can much more easily reach that power goal with less drastic modifications, and ultimately would probably save you money. Depending on the LS variant you chose, you could be as little as a cam swap away from 500 hp, though for most of them figure on heads/cam or a mild FI setup. Plus its a more modern engine. Building a big horse big block is also pretty straightforward. Better heads, cam, and some more compression and you're there.

Werd.

The downfall of the small block is the head design for the first 50 years... Whereas with LS motors you can make real power with stock heads just ported. A 6.0 can hit 500hp easy.

ls also get you almost if not 2x the fuel mileage over older stuff.

as close to bolt in as can be to older engine style .

real easy to stand alone wire the stock harness by your self .

and a ls style 5.3 stock was basicly 300hp . cam/springs/headers/re-flash pcm = 150+ hp and only loose around 2-3 mpg average .
