Truck again

I thought I had posted about getting my trans back from Sierra and transfer back from the shop a few weeks ago but I guess not.Anyway-heres a average shot of it sitting on the HF dolly. 727 trans and 208AM transfer w/new chain.

 So today I stopped by my machine shop-B&B-Excellent job!- and was intending to stop by to say hi and pay my bill. Ended up making my CRX do another day of truck duty with all the parts handed off to me including head, crank, block and more.

The clearance at the front tire is more than normal and the clearance at the back is a LOT less. 1800# car and 400-500# of hardware.. LOL

Thanks to my neighbor for helping me lift the block out of car and onto engine stand.

Pistons got dished to 18.25cc from a 15.5 stock

Block got brass freeze plugs and 0.056” taken off the top.

See this movie.

Please see this in the theaters so that movie studios get the message that this is what we want to see. And bring your tissues. GREAT MOVIE!

Temporary truck

Went up a couple Sundays ago to get our Christmas tree. The truck is still missing a motor so we drove the substitute truck up above Butte Meadows.

Zero deck

In the quest to build the most reliable and inexpensive to operate motor for my truck I figured out that I had to have a zero deck motor with the 0.043” thick headgasket acting as the quench distance for expansion. This distance will yield the most power while simultaneously cutting down on possible pinging. Long story short-after research a smaller quench yields higher compression but offsets that by majorly decreasing pinging. Google it-I’m not explaining properly.

So I went to my machinist Tuesday and we put the crank in along with a few bearings and put one piston on the longest rod and assembled it to the crank. Then we measured how far down the piston sits in the cylinder to determine how much to shave off the block. Initially my (very excellent) machinist wanted to just take 0.010 off the block but I pushed for the procedure we did on Tuesday. I am VERY glad we did it as the block turned out to need 0.055-0.057 taken off to achieve the desired zero deck!

WoW! If the block was not zeroed it would have meant a quench height of about 0.099 which would have meant not only would I have given up 40-50hp, but I would have been buying jet fuel to stop the pinging.

No pictures yet but with the tranny/transfer sitting rebuilt in the garage, and my IFSJA replacement driveshaft leaning against the wall-I am antsy to get started.
