I have a customer thinking about building one. Alky 2bbl and 410 cubic inches is the only rule. Anyone seen this done?

2bbl LS engine for circle track?
Have a tech member running one. Don't know the class an rules, but he has a front distributor that I believe is because of rules. Do not recall the details.
I don't see why not! If you can do it on a conventional SBC you could do it on an LS engine and it would love it.
Can you run an adapter to make it fit a standard 4150 intake?

Doing an Iron headed 6.0 with an RPM intake and a 4412 going to put in a car as a test see how it goes.
Meaning see how it stacks up against older conventional SBC's.

we are getting alot of resistance here. So we want to show the promoter this can be done and wont be a runaway.
Hopefully we don't have to run a front mount distributor.
Yes, a 4bbl intake with an adapter.
This is for a modified, and can run an aftermarket head, just no aluminum blocks. He is making 530 hp at the flywheel now with a 2bbl, 406 with 227 heads.
We are going to try and get as much compression as we can, use an L92 head with a hydraulic roller cam. Trying to keep it fairly cheap since they may outlaw it after one race. He says if they kill it, he will put it in his street car on E85.

I think a well built 5.3 block, with a 4" crank, and around 13.5:1 with a good cam and a decent set of heads would make quite a bit more power than that. I'm not sure how good the 2bbl carbs are you are using, but I know the stock stroke 3.905 bore 5.3 block I just built with my custom cam and dart heads made 500+ to the tires.. Victor jr intake, stock rockers, stock lifters.. *4bbl and gasoline*
are local track is stupid as well. Id love to build an LS circle track car. it would be a ton of fun for sure
A guy work with is putting together a iron Vortec headed 2bbl motor for dirt roundy round. We had talked about doing a iron headed LS. But rules around here limit valve angle to 20°.
