I'm getting close to putting together my stroker engine. Just going with a simple 383 topped with Ai's 200cc heads along with their 232/242 108 cam. Lift is 0.615 on this cam. I already have a Scat forged crank. I'm looking at rods and pistons now and just wanted some input from those that have more experience with this in case I've overlooked something or am missing anything. The car is just a street car. I won't be drag racing it. I'll have fun with it from time to time of course and may even autocross it or due an HPDE event. Point being, I'm not trying to set the world on fire with my combination. I just want a solid reliable build.
Since I need rods and pistons and am an engineer, I've tried to put some thought into my choices. Or, I'm just over thinking this which is typical of engineers.
I'm looking at Mahle forged pistons for a stroker running 6in rods. They have been recommended to me as being a quality piston with good sealing and low friction. They are listed as being 406g too which is lighter than the 5.7in rod pistons from Mahle.
For rods, I'm torn between H or I beam. Scat's procomp I beam rods are 605g, $300, and rated for the power I expect to make. Scat also has H beam QLS rods that are 569g but $550 for the set. I'm not trying to be cheap with my build but my understanding is H beam rods can be more difficult to fit the block and clear the cam. Is this correct? Are they worth it?
Eagle also has H beam rods but they are much heavier than the QLS Scat rods and only a little cheaper. Are Eagle rods that much better than Scat's?
All the rods I'm looking at are 6in, clearanced for strokers, and forged. I see no reason to go with 5.7in rods due to cost and the components being heavier. I realize I might not being going with the lightest components out there but I figure I might as well try to put some thought into my selections.
Opinions? Suggestions? Anything you think is relevant is welcome.
Not sure if it matters but the block has had steel 4 bolt straight caps installed with ARP studs. I intend or hope to run the stock windage tray and oil pan.
Thanks
