New Engine for the Challenger

[nocooler]

Big cubes, small intake port -sure does makes torque. Looks like a tuna boat motor! 

[Steve Wood]

you got it!  interesting combination but it should last a long time

[nocooler]

My 346ci LS has a bigger intake port - I can't image how the torque delivery will feel with 180 more cubes

[Steve Wood]

with an autocross style suspension, it should be interesting!

I think the CNC'd LS6 heads I have on the shelf have a 225cc intake runner... and flow about 316cfm at .600"; which is pretty crazy for a small motor.

PS. I think Steve's Challenger project shall now be dubbed: the Tuna Boat.

Mike mine are around that size and flow the same. I wish mine still had the powered metal guides and ls style valves. But I paid like $800 shipped for them - BNIB patriot stage 2 ls6 heads. No one wanted them because everyone on LS1notech thinks they are junk. Car picked up a solid 10mph with them and a cam.

Do I have to ship you a crowbar?

[Steve Wood]

you may have to stuff yourself in the box with the crowbar.  I am waiting on a friend to help me, but, it's been two months since he said another two weeks..

I am trying to get my shop cleaned up and I may just try to do it by myself here.

If it was dove season I'd offer to help, Steve.

[Steve Wood]

LOL....
