I have recently cam across engine troubles with my 84 corvette. I am looking to do either three things, first is get my engine rebuilt, get a different motor, or purchase a rebuild kit and also do some mods. I dont think I can afford to get a new motor I am not looking to spend over 2500 thats counting labor to install. I found a company to put a rebuilt in it that is bored over 30. It comes with a 3 year 50K war. It cost 2400, but I found some rebuild kits for sale starting at 199.00 thats the factory rebuild. Then I found one for 35 more hp for 250.00, its called street master rebuild. And I found another that has 11-1 compression for 549.00. I am looking to get more HP but keep the car street drivable. I dont want to have to get a stall kit or anything like that. I want it to get some what good gas milage and have all my digital stuff working normaly and be able to use my trans and comp. What do u suggest, get the rebuild that is bored over 30, by kits with the price going up not counting labor and no war. and if you think i should get the rebuilds what one is the best deal. REMEMBER I want it to be fast but not a drag car I want a relieable startable car all year around and be about i dunno 14.2 or lower in 1/4 let me know thanks.

GM offers a brand new crate motor that is a 350 cubic inch 200-250 HP engine. Right where your stock motor is. It sells for about $1300. It is all brand new 4 bolt block. Your stock block is a 2 bolt block. Comes with a 3 year/50,000 mile warranty. Check out the GM parts sites on the web. Your local chevy dealer should be able to get this for you. New better than rebuilt.

 

Anyone of the appropriate crate engines would be the easiest. A head and cam upgrade would be needed if you rebuild your engine. The stock intake will need a little port work to get the flow numbers up. For aftermarket intake alternatives look at the X-ram (I seen one is for sale here in the forum), Offy or Edelbrock SY1.

Ok so if I get a rebuild kit that gives me 11-1 compression and I get a new intake system what will that do for me? How much HP do u think i woul have? Remember I still want a street every day driven car, I dont want a car that needs a stall kit or a car that is a strip car. I was told the 11-1 will have to need racing gas but some one told me otherwise just premium gas would be fine. So get back with me soon thanks.

With your emphasis on 'street', 10:1 compression, aluminum heads for pump gas. Call one of the cam techs for cam recommendation. Most any cam that works well with a tpi works well with the crossfire. Crane 2040 is one that comes to mind.

HP? Depends on what you decide. There is one Extrude Honed Crossfire that has dyno'd a little over 320 HP (on a built 350). Some of the Crossfire style replacement manifolds have a greater potential than that.

There are forum members here that have real race experience that might offer advice. 84vette and CFI-EFI are couple of them.

 

well,guessing its an auto u dont' need to upgrade to a higher stall converter for a mojority of the aftermarket cams offered.it would help but not needed. as for the GM perfomance parts crate motor is a great alternative and would make a bit more power than ur stock motor too.

 

Do you care about emissions or not?

If not i'd switch over to carb, and put some vortec heads and a mild cam onto either your original rebuilt motor, or a Goodwrench motor, and call it a day. Just keep it to around 9:1 compression and youll do fine on pump gas and probably hit low 13's with decent mileage

 

You don't sound like much of a, "do it yourselfer".
And that's fine. I just want to understand your wants and needs as best I can. With your budget and intended (my interpetation) participation, I would recommend a crate motor. Who would install a "kit" if you bought one? A $1300.00 long block, like HWoods suggests is going to max your $2500.00 budget. Installation will run $1000.00-$1200.00 for labor. There will be ancillery expenses, too. Does that long block come with a water pump? You aren't going to lay that fresh engine down on 19 year old mounts, are you? Plugs, wires, cap, rotor, oil, filter, all are cheap, one by one, but they add up. Are you going to have the rad checked? New hoses? It would be real easy to suggest this or that for upgrades, but it looks to me that a replacement is about all you have "room" for at this point. If I have made some incorrect assumptions, I appologize. One guy jumped all over me saying "you don't know me!" because I tried to read between the lines and gave him low budget advice. That is the reason for the advance appology. I am only trying to address the situation, as I read it. Good luck, and...

RACE ON!!!
