Generation IV Internal Engine - SBC Pistons in LQ4?

i have a set of flat top ross racing pistons for a 383 that i CANNOT get rid of so i was wondering if theyd work in a 370 with minor mods? they would end up in the hole a little, i know, but i do believe that it would net me ~9-9.5:1. i even nhave a set of total seal rings to go with them so all id need is a decent set of rods with a .927 small end. yes, no, maybe, im crazy?

anyone?

The SBC pistons, if I'm not mistaken, are not built to clear the reluctor wheel on these LSx engines. That's the biggest issue I see immediately....someone else can surely elaborate and expand on that.

tht means the ring land layout is completely different so i may not be able to use em anyways..ugh

Well, Like matt said, the SBC piston isn't designed to clear the reluctor wheel on LSx engines, so you'd have to check that and modify them in necessary. Remember, what you do one, you need to do to the other 7 to balance them all.

Also, the SBC and the LS1 have different bank offsets. By bank offset I mean how far the passenger side (1,3,5,& 7) sit further forward than the driver side bank (2,4,6,& 8). So, because of that the pin boss may rub on the sides of the small end of the rod so you'd have to grind that away as well. I hear of people doing it, but i would rather not.

Just my 2 cents.

Depends on the compression height of the piston you have but if they allow you to run a 6.125 or longer rod they should clear the reluctor with the stock stroke fine. If its a typical 1.125 tall piston you could run a 6.300 long rod but you'd have to modify the rod for the SBC offset possibly.

Yep if you used it in an LSx stroker app you would have to do that and you might get into a bigger problem than it's worth depending on the piston design. In the "olden days" we had to run pistons and modify them on #8 ourselves. I probably had to make my own LS1 #8 piston a hundred times, so it's a lot nicer now.

Plus now we have real on center LS1 rods so the rods don't have to be modified all the time anymore. It took a long time to convince Eagle to even make LSx specific rods but now they sell out all the time. Unfortunately they're almost always all sold out even as we speak again.

this would be just for a 6.0 .030 over. ill pm you specs of the pistons but i believe the compression height is higher than 1.1 by quite a bit.
