Still looking for an engine or possibly still might just build one depending on how much time I have this summer. I would like to maintain at least 15-18 mpg, and be able to continue using it as a daily driver. It also has to fit under the hood becuase I am not looking into refabricating the hood or buying a new one.

- Here are a few links to engines on eBay that I found. They look sufficient, but I just dont know enough about this process to know if they are what I am looking for and if they will work for my application.
Any input is greatly appreciated, thanks!

You stock ecm won't work with that 383 for sure, I didn't look at them all but some things you would want if you intend to use the stock ecm and injection are;
- keep your comp lower than 10:1
- cam should have a LSA of 112-114

Are you keeping the CFI and stock ecm? If so crane makes some cams that will work, the 2030 and 2040 are the most common and if your not into porting your stock manifold the x-ram is a alternative for a modded motor.

Other than MPG, what else are you looking for? Even with a mild motor with the CFI you should easily get better MPG than your looking for.

I saw the one with the Vortec heads, it won't work with your CFI either

Ideally I would like to just take the crossfire out all together and just start from scratch. So if I am not using the stock ecm and injection what do you think would work well?
-Besides good MPG I want to put down more torque and power, not really into the track scene yet but I just want to have a little more fun around town:devil:

One more thing, If I do get rid of the stock ecm and CFI then I should be able to make that 383 or the one with Vortec heads work, right?

Thanks for your help js292, much appreciated:thumbsup:

If your going carb then you options open up alot more, and yes the 383 would work. I'm not a fan of going carb and it's not as easy as it sounds I'd keep your CFI

If it was me I'd freshen up the bottom end if needed, get a set of edelbrock heads 170cc, x-ram or port you manifold, crane 2040 cam, and a set of 3:54's.

One of the best mods I made to my 84 was installing the 3:54's, it really made the car feel more alive. Just my two cents.

I'd consider keeping the Crossfire for Economy and Ease. Changing to a carb looks easy, but from what I can tell, it's a lot of work.

So keeping the corssfire wont really make the new engine lose alot of power will it? And are these engines on eBay garbage, is it even worth buying one from them?
