We are talking about going retro look like the late 70'ies or 80'ies when the SS ran 12000 and most of the used rear wheel weights. a

It depends on a lot of things in how the pump is built. I wouldn't go less than 32 degrees before TDC,. I run more than 40 degrees before TDC.

Your correct to mess others in class.

Does anyone know someone that makes IH rear wheel weights out of plastic or fiber glass. Thanks in advance for the help.

Thanks for all the answers. I running 656 rear end in LLSS with good part in it. The bet came about as another guy is starting to build a LLSS and he was thinking about using 560. I told him that he would not have enough front end weight. I am working on getting more front end weight. On good track I can't run draw bar at 20 inches.

thanks for information. I believe i won a case of beer

Trying to find out approximate weight difference between a 560 and 460 rear end and transmission and a 460. Thanks

I just found this video of first pull of this year. Still had small pump and old turbo.

I am running a p pump and 3x4 turbo. If you are running 100 pump I would talk to a pump shop. I don't know much about 100 pumps and there internal timing. fire ring might be over kill but I recommend doing it right once is better that re doing it.

I would fire ring it with hiremax (sp) fire rings and head gasket. I am running over 90+ boost on stock head bolts. A rich motor runs cooler than lean one. You can go more on timing. I have run over 40 degrees advance just makes tractor harder starting. good luck Are you restricted to stock looking pump?

Your correct larger exhaust housing slows the turbo down buy can makes it harder to light depending on how big the turbo is. Have you tried changing your timing. More advance can lower EGTS. More fuel may help too. If you can I would inject water. How high are you EGTS. I try not to go over 1700 on my tractor..

30.5's on 656. Love looks.

Good luck at the pull. Love the looks of the 650.

Facebook another view of my run

We did pull off and still tied. So we split the prize money. Good Steve.
