Default LS3 C4 Corvette Swap.....

So its been almost 2 years since I went down the N/A rabbit hole with my ls3 ford focus. After several attempts to make big power on the focus I threw a rod and destroyed the motor. Since then I put a turbo 5.3 in the focus and have had alot of fun with cheap easy hp. But i have had an itch i just cant scratch.

So I decided to go down the N/A path again.

I recently bought a 1985 C4 Corvette Auto with a blown engine. I have since then removed the engine and transmission and started the ls swap.

For now I am going to use a stock block and heads ls3 with a cam and intake.

I am using a super t10 transmission

The car weighed 3166 when I got it. I am hoping to get it down to about 2700lbs

So i have installed kirkey seats and have a 5.3 I had laying around the shop installed for mock up.. I have to build an adapter to go from the t10 to the stock c frame.

Well......I'd have kept the OEM intake and had the radius-rod mod done to it. But I guess the fun factor won't suffer too much with a 2700 LB 'Vette.

best of luck....have fun!

I ended up buying an l92 6.2 from a cadillac. I got it stripped down today.

I also finished building my c frame adapter

I bought a set of headers for a c6 corvette and only have to modify one pipe.

Very cool.

Word to the wise, check the rear. If it's a Dana 44 you should be good. If it's a 36 just know they are more fragile. If there is not a sticker with the rear codes you can always look at the batwing and figure it out pretty easy

Post some pics!

Very cool! I'm finishing up the rebuild on an L92 myself. Should be a really cool swap with the 4 speed.
