Looking to replace my MP590 cam and this one looked like a good replacement. Not sure if it would give much of a gain or not? http://www.lunatipower.com/Product.aspx?id=1541&gid=247My present set up is a 408 scat stroker kit with 11.9 comp. 590 cam,ported eddy heads,super victor intake,750hp,TTI step headers. 904 trans,5400 stall,low gear set,4.56 gear and 30x9 slick

I ran a comp flat tappet extremely close to what you are thinking about at the same compression, same headers, same heads but a 727, car weighed 3450 with me. 10.74 at just under 124 as well. I always thought a good 1.875 header would have been a real nice upgrade. I bet a good roller cam and the header upgrade would pick the car up a good bit. 590 is pretty similar to that comp.

Just curious, what do you shift at and what is your trap RPM with your existing set up?

It will gain you nothing IMO. It has about 9* less duration @ .050 on the intake, witch will give your motor a lower torque peak and less HP Your current 60 ft. is already better then your ET suggests it should be. You dont need more torque, IMO just more HP. Maybe you have a fuel issue holding your top end back. This is all based on if the SB MP 590 has the same duration of the BB MP 590 witch is 272* @ .050 And I believe it does, just never measured a SB one myself. But I know how MP worked, they would just cookie cut everything the same. If you want to change something, go BB

I think the small block 590 is [Email]265@50.[/Email] Don't think the swap to that comp is worthwhile.
My 416 layed over the last 150-200 feet with that small header and small head. Shift at 66, trapped at 7.

Keith .. You sure the 590 small block cam isn't 265. I know the 557 is like 257, doesn't seem right one step up from 557 to 590 would be 15 degrees I think the 620 for a smallblock might be 272 I have just read several links about the 590 being 265 But I have been wrong before... Lol

The 590 is 271- 272 @ .050 depending on which one you measure. Keith
When I said 272, thats just what I got. A 1* or so difference is not uncommon and expected between grinds and personal measurements.

The 557 is 251, the 257 is incorrect The 590 is 272, the 265 is incorrect The 620 is way bigger yet, 280 sounds about right
Yes.. To clear up my screwup........ I got the 265 from both the Summit and Jegs online catalogs. Wish they would fix/ update them so schmucks like me don't look so dumb

http://www.4secondsflat.com/RB%20Cam%20Specs.htmThe STX-22 was sold by Mopar back in the 70's as a purple shaft cam. That was my orginal cam. The current cam is a 590 but ground by a different cam grinder. I contacted Zippy and he comfirmed that RB no longer grinds the 590.
