Looking at this pan for my 421 stroker. Have stainless works longtubes and wondering if the fitment on this pan with lontubes and such. thanks

I believe thats the pan i ran with my 383 and hooker longtubes. With a lt1 ministarter, no issues with clearance. Fit great

Orr, I talked to canton amd told them my stroke and intended rpm amd they steered me towards the 246t power pan. They told me that small kickout on pass side there is a considerable hp gain with windage by catching the oil thrown off the crank at high rpm. I guess instead of hitting the wall and splashing back on crank it elimibates this. Told me a % gain has been documented esp big stroke applications. Wondering if the pan will fit. Any exp with this pan?

I see no difference between those two pans? Dimensions look the same and have same description from canton. Oh well they would know best, i have not run more than 3.75" crank but i turn 7k rpms and the pans built in windage tray and scraper seem to work great. I have no way of telling how much better it is vs a stock type pan however. Cutting down windage and aeration of oil is definately a good idea tho.

I'd think that kickout would be a good deal if your not running a windage screen bolted to your main caps.
