I have a '91 S10 2.5 4 cyl backed by a T-5. I'm kicking around the idea of a V8 swap. I know the bellhousing won't work but can the NWC 4 cyl T-5 be upgraded to World Class spec to handle a bone stock mild 350? Thanks.

No. But there are performance upgrades that can be done to the non WC. I see you are from PA. There is a guy in Lancaster, Ed something or other. He is at Carlisle every year - he can hook you up.. If I can find his card , then I'll forward the info.

Do you mean Ed Hartnett?

The input shaft and front bearing retainer are too long on that transmission to work with a V8 conversion. You need to find a 4.3 transmission or a Camaro V8 transmission.

Do you mean Ed Hartnett?

Yup. He has always treated me very well and never led me astray, and he doesn't know me from spit.

Ed Hartnett is in the Philly area; his phone number is 610-623-9381

Another North Eastern T5 guy is Dave Reed, he's in CT and hes on here as well (Reed0380) His phone is: 203-265-6888

I've got new parts, no cores and we don't rebuild them either. PM me if I can help

T-5 upgrades

The gears in the 4-cyl or V-6 T-5 5-speeds are too frail and spindly to handle the torque and power of any V-8. You need a V-8 Camaro T-5 in either world class or non-world class (both have the same strength) and put the S-10 tail-housing on the back of it. It is more involved than that. Please feel free to call me at ********* ****** or PM me.
