374 Olds 350 stroker build

[olds307 and 403]

Yah, I will keep the studs as spares, what is less than $100 in this fortune I am spending. The 7/16" balls were $25, no loss. The Poly Locks, $50, again spares aren't so bad. I am missing a couple of 3/8" balls, $22 for a set. If I get the 3/8" to 7/16" studs and 3/8" balls is only $100 more🤷‍♂️.

Isn't that something like 50+ LS engines?

Isn't that something like 50+ LS engines?

Yes, pretty close😳. I just can't do it, NO LS! Another new Challenger was almost purchased and the Cutlass sold, it was a serious consideration. My block should be ready and hopefully the crank is ground. The Mahle pistons hopefully are being made right away, then just balancing and assembly.

I bought one of last set of Accel 8.8 25 ohm race wires. Holley would not ship them to Canada, Cutlassefi got them from Holley for me, they were under $20 a set! I bought a set of these in the 150 degree? angle boots about 10 years back after the MSD 8.5 Superconductor plug wires cracked on the #1 plug wire. I do like the MSD crimper better than the Accel one. Geeh, I sure miss that hot running 403🙄. They have held up really well but it is time for new set for the new motor. These being straight boots, I made them a bit longer. They range from just under 50 ohms to 125 ohms per wire, extremely low resistance. The wire markers I bought separately, they work great.

I talked to the machine shop. Of course more work they had sitting that they had forgotten to do, have become priority🤔. Either way, pretty sure the block is done, was hoping to hear back this week that the crank was ground, I did not hear back. They gave a heads up on the Mahle pistons I have ordered, which hopefully is wrong. They have been waiting for parts from Mahle that keep getting the delivery date pushed back, we will see when they get done. The bad part, like every machine shop, the shop they use to balance cranks is two months behind. When I talk to them next week, I will try and glean what will be the quickest way to get my crank balanced. I will hopefully have bearing size known and order from them from Cutlassefi. I will contact him with the undersize and see if he knows where Mahle is at with their piston run. I am hoping to have the short block together before the end of August, otherwise Harvest could start and could go to November, it means possibly 6 days a week at work and no time to do this. No if I can find a way to have the kids pay for their cell phones and hopefully my oldest gets a good paying job, I could buy a second Challenger GT. Unlike trucks, which almost don't exist and even used are ridiculous, there is a nice White one sitting on the lot optioned how we want for 50 grand.

Only $50k? Even with the exchange rate that's about 30 Pontiac Vibes. Granted, total HP/dollar is about even.

One tool I always use on my engines is a bore specific tapered piston ring compressor , once you have used one of these you will never use a universal ring compressor again.
