what can you safely bore and an stroke an LS3 out to?
do they have longer sleeves then LS2
can you get 454 and stil be hi milage car

 

500 rwhp and awesome streetability

 

I'm loving my 418 10.7cr / WCCH stg 2 L92's and Richard spec'd cam setup. Still breaking her in but I've gone 12.1 at 113 so far with more on the table.

 

I don't have a 416ci, but a bunch are running around here from a local shop thats been pumping them out. They're all around 530 RWHP, L92 hand ported heads and ported L76 intakes, with 230ish sized cams. They idle like stock.

 

Anyone have any updates?

I've decided to go this route. Seems quite a few of you are getting some great numbers with near factory stock idle. My preference is to have quite a rough idle.

I've been thinking of the LPE GT1-1 camshaft. Of course all supporting internal and bolt on mods.

Comments / suggestions??

Thanks,
Jim

 

Do it.....you should have a nice streetable 540-550 RWHP set-up with an aggressive cam.

We've recently dyno tested one that went right over 670 flywheel horsepower with a 240s duration camshaft & pump gas. I've seen 560rwhp or so in a M6 car.

 

At your shop? If so you got a mods list and graph?
