[barrie]

Anyone advise on what choice of gearbox to go for to fit a chevy big block (7500cc).

Hi,

I think that you have three good options,

one an old four speeds like the ones that use the Corvettes and Camaros in the late 60th´s and early 70th´s, is a a Saginor 4 speed.
Other option is to use a Tremec TKO, that will accept the torque of your engine.

The last option is a Tremec T56 like the ones you can find it in 90Th´s camaros, some Corvettes, ate Astom Martin V12 and in the Chrisler Viper.

The choice is yours, but any of them will cope with the torque, I prefer the TKO or the T 56, at least the last two speeds will help you to run at high speeds without stop every 100 miles for refuelling.

Hope this help.

Jesus,
Thanks for our advice, what do you know of borg warner r380's I believe they are used commonly in Land rovers and Range rovers do you know if they will be up to it. By the way I have had the engine tested and it pruduced 470lbs/ft at 3500 revs.
look forward to your reply

Hi Barrie.
I don't think the Rover box will be upto the job, not with that much torque.

Dave are you still there!!!!!
I am trying to identify the current box can you help.
Its got Borg Warner stamped all over it so Im allright with that, the identification numbers dont seem to tally with Borg Warners. The numbers I can find are as follows:13 32 063 914, 13 52 066 911, 1c 51 097 901 ( the little c is the opposite way around I could find anything on my keyboard to represent it)and Finally R3. Hope you can help!!
Cheers!
