MY first post i have a 1993 caprice with a 5.0 i need any hints, tips, tricks little things that will make my 1993 move her ass a little bit faster, thanks

Papa D

Intake and exhaust will be the first things you wanna address. I am not real familiar with the 5.0. is this a TBI engine?

Since when did gm and Chevy use a 5.0 engine......I thought that was Ford

The 5.0 was a 305, it was used I think mostly from 77 all the way up to 93. Should be a TBI. Depends what your goals and budget are, that motor doesn't have a whole lot of potential, but some things you can do would swap over if you wanted to get a 5.7 later, like exhaust. Sticking with what you have, best bet would probably be to throw a cam in it.

The 305 engines are Chevy's 5.0s

I'm looking to do the same thing in my 87 Caprice and plan on putting a new Carb, Intake Manifold, Cylinder Heads, and Cam, and dualing out the exhaust to let it breath. In a 93 however you probably have TBI so I guess some of the options I'm looking at wouldn't benefit you.

With that amunt of work, why not just do a crate 350?

^^^^^ WELL SAID get a 350 cid and let the build begin..More cubes more potential..No use throwing that money in a 305 when you can build a 350 at the same price for WAY more performance..

Forget spending any amount of cash on your 305. Instead save up some cash and go for one fo these like I am.

As you can see the clearly easier and more logical answer will be just getting a 350 lol. I'm only keeping my 305 for the challenge and the fact I don't like to do the norm. But honestly a 350 will make your car ALOT faster from stock and upgraded. But this really all depends what you want out of you're car performance wise? My car is just gonnabe a cruiser for me.

Old Bones

I don't hate my stock 305 , it always starts , runs well , but it's a slug.
IMHO beefing it up is a waste of $$ when a 350 (same block) will fit right in and double your horsepower.

Exactly, same size and weight, why not? I'd like an engine from Steve Morris, but that's kind of a higher price range...

My best friend had a 1986 coupe with the LG4 305 4BBL engine rated for 165 HP and we were pretty happy with it's performance overall. It was a low 62K mileage car owned by an elderly guy who kept it perfectly maintained. It had the optional 2.73:1 rear gears in place of the stock 2.56 setup ordered that way from the factory as a $21.00 option along with the equally dirt cheap 41.00 F-41 suspension. I did a few tweaks to the carb on the secondary side, ran a slightly cooler plug and t-stat to keep the 305 from pinging which has the adverse affect of dialing back timing and power and ran a K&N filter. The biggest performance booster was replacing the stock cat converter with a Magnaflow unit to take advantage of the extra carb flow. It wasn't a race car but hardly a slug and it would easily light up the rear tires. Another thing to pay very close attention to on stock C4 equipped 305's is the TPS sensor. If it is even off slightly you will lose power and response along with erratic and or late lockup torque converter lockup in third and 4th gear. A GM service manual is a must with these often misunderstood cars. They are getting pretty old now and things need replacing/rebuilding and checking.

Crime Scene

If it helps any, its guys here in Lagrange Ga that builds Chevy motors and Chevy Motors only for a living. Ive seen them use a set of 350 heads on a 305 block, and a lot of the 305s they built has put a lot of 350's to shame. IMHO, if the 305 equipped car can sit for a while and the owner although could easily opt for a 350, but rather enjoy the challenge of building the latter, then i say throw some 350 heads on there and lets see what you can do....

The main difference between the two is size, there is no reason that whatever mods you do to the 305 that make it beat a 350, wouldn't make that much MORE power when done to a 350 instead. Plus they don't cost any more, and they don't weigh any more, not a hard choice if you ask me.
