I used the 1/4” thick Dynaliner that you linked to. If you use the factory style insulation you will end up cutting about 1/2 of it away because it doesn’t fit behind the vintage air according to the...

A big time corvette guy that lives right by me owned that car when it was in MD. I think he sold it to the place you bought it from for about the same price you paid. Enjoy!

Well the engine was bored +.030 20 years ago. It was only honed an additional .001 to put a fresh cross hatch on the bores this time around. So, boring and honing with a torque plate is a moot...

I like that math. The one with all the leak down was firing so who knows. Hopefully the new pistons and modern 1/16” rings help a bit too. The compression ratio probably got a bump to around 10:1...

The problem ended up being the piston. There was an area on the ring land that was rough feeling and I assume they is where the air was leaking thru. Put in the new pistons and he did a leak down...

It was not done with a torque plate. He doesn't have one for a Pontiac. When he tested leakdown with the new rings he told me that he did it with just the head bolts for the bad cylinder snugged...

I’m waiting for him to give me the final flow results. The most recent I saw as he was working on them were 159 @.200 and 220 @.500. They flowed around 230 at .600 but my cam is only .479 lift of...

Almost dyno day...another what’ll it make

I’ve refreshed my 400 and it is about ready for dyno time. I needed to replace the leaky rear main so I decided to swap out the 041 cam, get the heads ported, and upgrade to forged rods. Pistons are...

Well now I’m tempted to get my 400 dyno’d too when it’s done in a few weeks. My builder has a dyno so we will see if the budget allows. Spoke to him about it today and he charges $750 to do it.
