Just looking for feedback from guys running this pan . Its the one im using on my RHS 481 . I know my motor should have a dry setup but it was out of the budget.

[/URL][/IMG] I went with this pan cause it clears up to a 4.600 stroke crank without using spacers.

It seems like the best road race pan on the stock stroke stuff, but I worry on the 4 inch stroke stuff.

Kurt mine is a 4.5 stroke so now you have me worried a little .

i have one, though I have modified it a little bit to increase its capacity (per kurts suggestion)

I can tell you it clears a 4" stroke no problem

The windage at 4.0 is getting bad enough that GM would not use a wet sump pan, that is one of the drawbacks of the skirted design. If you are low rpm street driver it might be ok, but if racing is in your future I would use some type of dry sump with that stroke.

How many minutes do you hold the engine at 7800rpm? What the heck are you doing!
I see pressure problems at 6500rpm under 1 minute with the larger stroke, the stoke stroke stays stable at 1 minute.

Kurt
Not minutes by any means since its a drag car. 9.80's in a 3200lb door car

Been on the dyno with 5qts in the pan with no pressure drop, also no pressure drop in car goin down track.

Just to be clear, this is with the autokraft pan the op was asking about
