The 300 six is generally considered a "big block" six engine. Never seen a ZF in a 1/2 ton myself, but it may have happened.small blocks like 300-6, 302, and 351W. and I don't think half ton models came with these, they got the M5R2.
ZF S5-42 were actually factory equipment in a number of Ford heavy-duty trucks for a few years -- '87-'95 F250 HD’s, 350’s, and 450’s behind Windsor blocks, 460’s, and diesels.
The overall length of the ZF S5-42 in 2wd is 26" from the bellhousing face to the rear output and it is 14.5" tall. 2wd version has a 29-spline, 1.495" diameter output shaft, Spicer yoke on it is ZF part #1307304079 or Ford part #E7TZ089A (local dealer charges about $50.)
So, just so i can get this straight, '87 - '95 ZF S5-42, with the 300-6, 302 and the 351W are the trucks that I'm looking for to get a small block tranny bolt pattern, right?small blocks like 300-6, 302, and 351W. and I don't think half ton models came with these, they got the M5R2.
Ok, so then anything after 97 will most certainly be the bigger bolt pattern, as I am understanding it now. Or at the very least something that won't fit to the small bellhousing pattern.I referred to 97 since it's the last model year for a SBF bell ZF 5 speed.
Model Year 99+ the S5-47M have the modular bellpattern when used behind the 5.4 and 6.8.
Any common fixes for this? Considering I'm running the P30 axles (That dont have a VSS) .... I am now left with no 'solution' for generating a speed signal. I know people have said there are driveshaft mounted solutions...but I have yet to find one at all.
