IBS timing chain recomendations

a brief history. i built a naturaly asperated ibs 4.3 (roller cam,202/160 valves, hardened pushrods, guide plates, crane aluminum rockers, studded heads, ported, hi vol oil pump, etc) for my awd astro van a few years ago. sold the van and kept the motor.

the plan is to put in forged dished pistons, I beam rods, and some cometics. tomorrow is the day i tare down my ibs motor. i pulled the timing chaian cover and the chain had to much play for a motor with 12k miles on it.

i was going to replace it with a stock chain because no one seems to make a double roller for this motor. it has a sprocket behind the top timing gear. which turns the ibs sproket. all of which fits under the timing chain.

im thinking that they don't make a double roller because there isn't room for it with the extra sprokets for the ibs. and it uses a plastic timing chain cover, not the syty metal style.

does anyone know of a stronger than stock replacement for the ibs 4.3's?

i think i know the answer..............:(its gonna be a no, but it doesn't hurt to ask.

Re: IBS timing chain recomendations

I would recommend checking with E-rue on the board he used to be big into the ibs engines so I would think he would be your best bet for figuring that out.

I know when I put a new chain on my so gt that there is quite a bit of play for even a new chain :roll:

Good luck with the search :D
