Thread: 400 sbc

You can use the crossmember that relocates the torque arm off of the tail shaft.

what would i have to change to make it go from FI to carb? and all that computer crap?

Just a couple things Torque Arm, you will need to figure out how your going to mount your exixting Torque Arm to something whether it is an after market one that doesn't mount to the tailshaft or figure out a way to mount it to the new trans. Speedo and all dash gauges if you are going with a 350 or 400 turbo trans remeber you are loosing over drive. If you go with a distributor be aware of the hassle of working with it buried under the...

You will lose all your gauges when you bypass the computer and on the fuel pump it will all so not function because of the bypass of the electrical but no need to mess with the pump because the manual pump will pull gas through it and all so the firewall will need some work for the firing system...Clearance issues so be aware and you can all so change the tail shaft on the tranny with a older model camaro transmission

I would try to leave the computer in. To control some of the factory gauges. The electic pump could stay. Just have to get a fpr to turn it down to carbed pressures. Tourqe arm i would go aftermarket.

If you wanted to use the TH350, there are aftermarket mounts you can buy to use your stock torque arm.

you may want to reconsider the whole transmission bit. It seems like you strongly dislike the modern electric transmissions but a 4l60E can be an impressive bit of machinery. A buddy of mine who autocrosses a 4L60E transmissioned silverado has a piggyback computer that plugged in for the factory transmission computer. This system of coarse allows you to fiddle with pressures and shift firmness etc. But it also allows push button upshifting and...

Pretty much as the question of the thread asked,everyone addressed the swap of a 400 it's self. I wanted to take a moment to drop in and add info about the 400 sbc.They have a limited bore size and if a bore is being considered I suggest you do a sonic ck first.While I worked at a Chevy Engine plant as a engine tester run testing them,we learned early on the bores on these 400's move around quite a bit.In fact in drag race...

Along the lines of the above poster. I suggest if you are planning to buy an aftermarket block for a small blk Chevy that you buy Dart or World. There are a number of Chinese made knock-offs showing up on eBay. Dart's new SHP block is a good alternative to the Lil M and you can throw a lot more power at it than a factory 400 blk. If I were building a street/strip SBC from the ground up, I would consider a Lil M or SHP.
