Re: 1986 Chevy C10 SWB Step Side

Yeah, I had an s-10 I drove for a couple years in the city,with a manual trans.your right too much foot work/stick.especially in traffic.what are you running in yours for gears? When we rebuilt my striker motor that was in my camaro we used a comp cams 280 lift my brother said if you go any bigger you start to have street ability issues I still have the stock rearend in mine.seems like it needs a little lower gearing like it's 273and it needs 342s or something I'm not racing the truck ,so I don't want to go too low.i like having a little top end.gotta get the right rearend under it next.

Jeff,
The rearend end gear is 3.73, with new Eaton posi. With the trans having around a .75 4th gear ratio, it does not have a lot of rpm on the interstate.

Going with a new motor, this one has to much cam to be fun driving slower around town, with the LY6 option transmission. The transmission gear ratios and spacing just make it hard with motor that needs lots of RPMs on the low end. Replacing cam in this motor with Comp Cams Hyd roller 205/204 duration, 4.89/ 5.23 lift, 110 centerline, installed at 106 degrees. It will initially go in the 65' short bed, with a turbo 400 switch pitch trans.

Putting in a GM create motor. What a difference driving slower ( not WOT), fun again. It has no high top end RPMs, however, for cruising it is great. Some gas in second breaks the tires loose. Still breaking in the motor. The motor itself is very quite, 3000 rpm and very little mechanical noise, just mellow exhaust music. Great throttle response, and really fun to drive.

The photos show progress on install. Will get some with install complete. Initial thinking on carb, is really nice. It is a Quick Fuel, ???, will get the number. Very easy to tune.

Great build thread. I like the way everything is so well documented with the write up and photographs. I'll be returning to this thread when i start working on my 87 Shorty.

Eric,

Thanks for the complement, and glad it may help you in some way.
Your 87' short bed, will be a lot of fun to drive, they are great trucks.
Pretty easy to work on, and lots of parts/options available.

Re: 1986 Chevy C10 SWB Step Side

Jeff,

Thanks for the nice comments. More cold weather here and some snow. Next warm day plan to get some photos of the engine compartment complete.

Replacing the radiator overflow tank again. It is a new one, however, it has cracked and leaks. Purchased new GM one, hope it does not crack. May only use two bolts to hold it in place???? the new GM one does not fit the inner fender existing holes. Adjust the attachment holes in new tank, however, not enough area to make all tank hole align with inner fender holes.
