I need some advice as to which direction to go. I have a 350 Chevy engine in my car and it needs a complete rebuild. Also I would like to up the horse power and fuel efficiency. The question is should I have a mechanic rebuild the engine, bore it out, change the cylinders and headers, and possibly add a TPI; or simply buy a new create engine and just swap it with the original engine? I do not have experience in engine work; however I am sure I can figure out how to swap engines. This is for a Daytona built on a 1981 Corvette chaise. Also there is a time limit on the project. It needs to be finished before the end of the year before the birth of my next child. Please give serious and mature advice only.

Buttom line new is new and rebuilt is used. If you were to rebuild your 350 it will cost much more then a new GM crate engine. Best deal in the market is the ZZ4 gm crate engine. Look at the brite side buy the GM engine and sell your engine to a clown that thinks he can rebuild it for less then a new crate engine and you can apply that $$$ amount towards the new engine

I'd have to agree with Edge on this one. I was facing the rebuild vs buy situation on the 360 in my Mopar. I decided to buy the 360 Crate commando from Mopar performance for 4k shipped. I never regret it one bit. Especially if there is a time limit as you said. Buying a crate can turn a project from days (rebuild) to hours (simple swap).Also consider warranties if they come with your crate. And in a pinch you could always buy a shortblock and finish it yourself for a project that is in between in the time and cost.

A mild performance motor will easily cost $2000-2500 to build.Just to get your block cleaned, checked, cam bearings, and bored it'll cost about $300. Then you'll need: $75 gasket set $40 oil pump $350 for decent pistons $70 to prepare & check rods $75 main & rod bearings $30 water pump $175 decent distributor $250 decent manifold $250 carburetor Heads: $200 stock rebuilt/$600 stock worked/$900 decent new performance $350 decent valve train $200 minimum if you go ARP hardware Probably other stuff I left out. Unless you just want the learning experience, I'd go crate built by people who do it every day and you get a warranty. KitCars.com Mitch |

I think I will go with consensus and buy a crate engine. Since I’m doing this I figure I might as well swap out my 4 speed transmission and upgrade to a 5 speed or 6 speed manual transmission. So I have some new questions:1) Where do you recommend I buy both the engine and transmission? Preferably from businesses that you have dealt with personally. 2) What about issues with passing emissions on the new engine. Are all the sensors included or do I need to take them off the old engine? 3) If I do change the transmission, will a 5 speed or 6 speed fit into a 1981 corvette exactly the same way with out alterations? 4) Can I simply get a 6 speed from a latter model corvette and fit it to my car? Is it the same bolt pattern?

Dr You can buy a GM crate engine from your local GM Dealer , as far as swaping your 4 speed to a 5 or 6 speed then I suggest you visit www.corvetteforum.com and ask the same question those guys would know what it takes to do the mods.

When I switched my 76 Corvette tranny out to a 6-speed Richmond, alot of the parts I ended up using were 1981 Corvette parts; the clutch linkage, the newer pedals, and other miscellaneous parts. The crossmember I used was not the 1981 one I purchased, it ended up being the original one that came with the car - although I had to relocated the mount a bit.I ended up not using the original exhaust system (went with sidepipes). If you don't have true duals, you'll probably have to switch over, because there's not a whole lot of room to run the pipes. The Richmond unit doesn't come up exactly where it's supposed to, either. I had to bend the shifter a bit to get it to come up in the right place, the tail yoke was from a 1986 Corvette, and the driveshaft had to be modified...however, I had already swapped the original auto tranny for a 700R4, then to a T5, then to the Richmond 6-speed, so I have no idea what the exact modification to the last driveshaft was. Now, if it was ME doing the same thing over again, I'd probably put in a blow-proof bellhousing - especially if you're going with a higher-horsepower motor. If your tranny lets go during some spirited driving, you want to be able to walk away with both legs. The Richmond unit was a bit pricy, as well. You can go with the crate motor - always a good choice - but you can source the transmission from elsewhere. For example, I got a 6-speed tranny out of a wrecked Dodge Viper for $500. The only thing you want to make sure you do is check the wreck: if it looks like the car ran into something, then it's a pretty safe bet that the car was running and driving just before it suffered from decelleration trauma; the tranny should be good. Hope that helps. Your pal, Meat.

Hey... just wanted to pop by and say that I am most flattered by the fact someone has tried to pass themselves off as ME on this (and other ) forums. Handy trick putting the "." at the end to get around the system.As an individual working in this Industry and gainfully employed by it, I take seriously the impact of this action. The representation you are making can seriously effect my reputation and business. Misprepresenting yourself like this can only cause problems. I'm hoping you'll reconsider. My name as well as several others you are doing the same thing with. To the point even, that you are having conversations with yourself on these forums... Grow up, get a grip, be yourself, get involved and contribute like every other person here. There's no need for this. DKOV - Scott Kovalik DKOV Motorsports www.gopc.com/F355/F355x.html |
