Hoping Jocko and the experienced others can chime in and help clarify some things for me:
I have a 1968 C10 with a 3 speed Saginaw column shift 250 I6
Gear ratio is 3.42 with 29" Tall Tire
I am in the same debate with myself as I have seen across Jocko's numerous posts and research threads: To Go T5 vs TKO 500/600
Regarding the T5: I have only been able to locate the S10 T5's that are Non-WC and have the below gearing
1352-201 GM 1990 S-Truck P 1st-4.03 2.37 1.49 1.00 5th-0.86
I am concerned that low of a 1st gear will just disappoint me and be almost useless - Anyone have any comment with this low first gear or the 3.76 options usability
OD @ 70 I should be in the ball park of 2300-2500 (Which I have read the 250 operating range you want to shoot for is 2000-3000) Does this seem like a good area to be in?
I also have some additional questions about the parts needed for the T5:
- What bellhousing hole diameter should the 1968 model truck have?
- is it the 4.686" dia index ring or the 5.125" index ring on a 250
- Flywheel: You keep and use the stock flywheel for your truck?
- Clutch / Pressure Plate / Throwout bearing: I'm alittle confused on these parts I have seen the mention for Astro Van clutch in multiple threads on here and the HAMB
Jocko recommends using the entire Astro kit for a V8 flywheel
Will this same situation apply for the 250 I6 flywheel
Or is it the other situation where I should go with the kit from the vehicle the transmission came from
Spacer Plate and Bearing Retainer Mods: I understand the need for these
- I was planning on Hot Rod Works spacer plate depending on what diameter bellhousing I have

I am really trying to debate whether i should move forward with the S10 T5 or go ahead and invest in the TKO and the future upgrade possibility.
The 250 is a strong motor and I plan on keeping it, but eventually ( i dont know when) down the road I think i would upgrade to a LS but that part is not top priority on the build list
Jocko Mentions he has about $1k in his swap vs the $3k mark for a TKO

Getting alittle intimidated and lost in all the small details
