bought another motor....

[Rangerclay]

So, yesterday I was out looking for a tr3650 trans for my bullitt... I came across a junk yard in the Mobile Alabama area and they had a motor and trans for sale... over the phone they told me that it was a forged bottom end block yadda yadda, motor was in a 2010 roush that had caught fire while racig ( supposed fuel line broke or something like that). Anyways I went and checked it out yesterday and it was in fact a bottom end 3v.. mahle pistons, eagle rods and crank, arp everything... I ended up buying the motor and trans for 1400 cash shipped to my casa. I know absolutely nothing about the build on the motor other than it turns and has compression on all cylinders. what do you guys think about the buy? should I take the heads off so I can figure out what size head gasket they used? is there a mathematical calculation I can do from the cylinder compression to figure out what size gasket was used/ compression ratio, so I can get tuning correct? thanks in advance.

great buy in my opinion. I would def pull the heads off to get a better look especially considering you know the motor was raced. youve alrealdy saved a bunch of money on the build so spending the extra couple bucks will be worth it

I wouldn't open it, it's doubtful the head gasket thickness will affect the compression ratio of an engine that was set up for a blower enough to worry about it causing tuning problems. You tuner will know how to monitor knock
If it looks good under the valve covers and from below with the oil pan off why mess with success?
You could leave the trans bolted to it, set up a battery on the starter and do a compression test on the ground. Do a leak down at the same time, if that looks good install it.

It’s on its way to the machine shop for a inspection, changing the head gaskets and porting the heads as well. Might as well while it’s there! I’ll update when it’s done and installed
