427ci LS2 sleeved, dry sump oil pump, engine build & install, 69 Camaro - Lateral-g Forums

Hey guys, I am new to this site, I posted up some back ground info in the “introductions” section yesterday. I am currently a member at LS1 Tech and I did an engine build thread there that I wanted to share here at Lat-G. I did a 427ci LS engine with LS7 heads, LS7 single plane intake, 4 barrel TB, and a dry sump oil system. The thread covers the engine build, engine install, dry sump oil pump and plumbing install, and some other stuff. I wanted to try something different using the single plane intake rather than the LS long runner intake. The goal was to build an engine with a long wide power band and good top end that would work well on the street and the track.

I worked with a local engine builder on this project. The engine was built from the ground up starting with an LS2 aluminum block from a wrecked Corvette. Working closely with the builder… I was able to do testing on the engine dyno to try out different cold air intake sets ups, test the digital control fuel system, and CTSV fuel pump. I found out a few surprises testing different cold air intake set ups! I wanted to tune the engine on the dyno exactly as it would be set up in the car. I didn’t want to have issues after install. This worked out great… since the install I have had no issues and the tune is perfect. This was a good way to go.

I swapped out my 450 HP carbureted 350ci gen 1 small bock for the new fuel injected LS engine. I documented the build and install with pictures from start to finish. The duration of the project was about 12 months. The engine was installed in the car this past August. I plan to continue the build project with a swap from the Muncie 4 speed to a T56 Magnum 6 speed (trans on order

).

I was pointed to this site by a guy on LS1 Tech. Look forward to being a member here at Lat-G

Welcome sir.

Sounds like a sweet motor.

Was your motor sleeved by ERL?

This is a very nice setup!

The attention to detail is over the top.

What does the car weigh full of fluids without driver?

Nice plans!

Sweet build!
Signed up on LS1tech the other day so I can learn a thing or two (so far not feeling so welcome there)
you are right at home here.

Thanks! My engine was sleeved by Nutter. They do quite a few 427's there.

Thanks! The total weight of the car with no driver is 3,420 LB. Weight distribution is 53% front... 47% rear. The aluminum block on the LS engine helped to take some weight off the front of the car.
