In the process of helping len h install a 400 eng. with stickshift in 38 bolt, his engine cast-ing no says engine is 70 - 73 from Mortec listing. My 400 is 75 model and it has no hole drilled and tapped for the torsion arm ball. There is a flat spot at the dipstick housing where a hole could be drilled and threaded and there is also a flat spot above the oil filter where I have no hole in my block, but len h says his block lhas a hole that seems the right size for the ball to screw in to. But, the question is, were there any 400s used in the standard transmission application? I went to the most logical spot that might use this set-up, the Camaro and from 67 to 81, the only near 400cid was the 402 and I think that is a big block. Someone stated that the 400s were used in the 70s in the truck. I had a 78 4x4 that came from the factory with a 400, but it was automatic. len h really wants to use a hydraulic clutch and I bought a 61 stepside for parts. It had a 307 engine (someone had welded mount towers for the engine mounts) and it had the bellhousing that was used during the 60 - 63 C10 that had the mounts on the bellhousing and the slave cylinder mounted on the passinger side. Anybody know of any factory stick applications for the 400 cid engine or any other hydraulic clutch housing applications that may work in a 38 bolt? Hydraulic seems like the best way to go to me.
Hope this will help, Len
