good morning I am in the process of laying out a new drive train for a S10 pick up truck small block chevy with a glide 4 link rear suspension. Customer has cut out all the stock mounting points on the chassis and alo the stock floor pan but it is being reinstalled. so I have nothing to reference motor will make about 650hp anyone have a s10 that culd give me some crank height measurements?

larry woodfin can help

Depends on the ride height and engine location front to back.

stock location as the firewall is not getting modified

A crude ruler measurement says I'm right at about 16" with a big block to the front mandrel center at ride height with a 27" tire. I made my own mounts and went with this height simply for hood clearance and header tube angles for the steering shaft. We made our own headers to fit.
Lotsa room under these things, we squeezed a big block with a Moroso 8" deep pan under a flat hood

I did move the center section of the firewall back about 2" and had to notch the crossmember a bit, probably about2" or so also.


Oil pan is flush with the crossmember.

I have my engine lowered as much as possible at the front. I'd love to raise the back end up more but header clearance under the floor restricts how much clearance I have. The goal would be to have the transmission tailshaft pointing at the diff pinion or if you want to be more specific, the crankshaft centerline should be pointing at the diff pinion.
