393 All-bore Solid Roller cam Ok guys I need some help picking my solid roller cam specs.
The cam is going in a stock stroke, 4.155 bore, 393 ci MTI built motor.
I plan on shifting @ 7200 and need it to be decently driveable and idle reasonably, but I definitely want an aggressive cam. I'm thinking ~240/245 ~.630/.630 112 lobe sep
Thoughts??

Re: 393 All-bore Solid Roller cam If you are going with a split pattern then go reverse split.More intake duration than exhaust.Also solid rollers have more driveability than hydraulic cams so I think you will be fine in that area.My personal choice would be a single pattern 245/245 650/650.Of course people do call me ignorant.Good luck either way.
I can shift faster than you.

Re: 393 All-bore Solid Roller cam The great thing with the solid roller lobes is you can get very aggressive without affecting driveability. If you plan on a 7200 shiftpoint, I would look into a much bigger cam. I would look at something in 25x range. Are you using LS6 heads?

Re: 393 All-bore Solid Roller cam Thanks for the input guys. I will be using MTI Stage III LS6 heads.
Has anyone used a reverse spilt cam on a larger bore motor? It seems like most people are using a R1 or a similar traditional split cam.
Is there anyone using a solid roller on a ~393 ci motor? I want to have an agressive cam but I don't want to overcam this motor. From what I have read you can go about 8* bigger on a solid roller than a hydraulic roller and have the same driveability, which makes 25x seem a little large. Comments??

Re: 393 All-bore Solid Roller cam You will have one AWESOME MOTOR and 10.00 second 1/4 mile car with that engine coupled with a solid roller cam. I would just stick with what JAYSON at MTI recommends to you and you certainly will be able to run quite a radical lift cam in that motor since your going solid roller.
I would just tell Jayson what you want the car built for and based upon your goals he will hook you up no doubt.
MTI rocks and so will your car!

OUt of curosity, how many cubes would a 4.060 overbore make on a LQ4 using the offset on a stock LS1 crank.
