Ya those aluminum header gaskets are the balls. One and done, do it right the first time. The copper gaskets worked great for me for a about a year now I have a slight leak but the aluminum never failed me.
 
Make sure you adjust this properly or that trans will be toast in no time at all.

For sure, my buddy is a mechanic and has reset many of them so hes gonna come out and do that and check everything over before startup to make sure I didnt eff anything up.

I have no idea why this stupid engine swap has been taking so long lol. I just feel like ive been going at it for so long and everybody else just seems to toss them in and go lol. I guess I did just get the motor 2 weeks ago or so, it must just be the fact Ive been waiting for it for like 4 months. I just want the stupid thing done. Ive been so freekin busy

I think next time I do an engine swap i most likely wont go so far into it. I spent so much time sandblasting every part I could get my hands on and painting that its taken more time than actually getting it working....

It's all about the details man. They'll makes or break what the end result looks like but they also take the most time to do.
 
She lives!!!

Yah for sure man.

Ok guys we got it all buttoned up and ready to go. Turned it over, got lots of flame out the headers.... Ooops, had it at top dead center on the exhaust cycle. Rotated the dist 180*, boom fired right up, het it to 2000rpm, sounded freekin fantastic!!!! Until the radiator decided to blow about 3 seconds after startup, water went everywhere, shut it down quick, found the leak, gonna need a new one... Dangit!!! somebody musta bumped it in the shop sometime over the last month or so. Oh well Im pretty pumped. It fired up on the first rollover, not a millisecond of hesitation, this things gonna be bad:thumb::woot:

well we didnt expect for it to actually fire when it did, we thought it would need more adjustment on the distributor, but it ended up being dead nuts.
 
Well searchin CL last night, my buddy found this, called the guy up, he paid $400 for it, put it in his 83 scottsdale and the engine blew a month later. He told me he wanted half of what he bought it for, so I got it for $200. Made by Northern in the USA!!! WOO:woot:Oh 2.25" core as well

Even through in the tranny cooler and the mounting brackets

thats pretty awesome .big motor.should move that thing around pretty good.awesome score on the radiator.those are good rads ive heard more than once.
 
Sweet, what type of antifreeze should I run in the alluminum rad??? Not ungodly expensive though.
 
I'm not a fan of those types of tranny coolers, but that doesn't mean there's anything wrong with them. I splurged on a big plate type, built much stronger and should cool better.

If you are going to run that cooler, make sure to flush it out as best you can. You don't want any PO disease that might be in there. That might go for the radiator as well, depending on how it looks inside.

Simple Prestone Green stuff for antifreeze.
 
if you want the best cooling and lack of corosion on aluminum use this ( pic ) with good antifreeze.

but reg old water and good name brand green coolent will be just fine.

and the aluminum rad will def help keep the 400 a little cooler.

Any antifreeze should work fine. You can do a 50/50 mix with water to antifreeze, or you can go all antifreeze.

Personally, I would do all antifreeze because I wouldn't wanna take a chance with any water in the system expanding when it gets uber cold out.

Never run all antifreeze! Water has way better heat transfer properties. Antifreeze is just some form of glycol which is a boiling point supresant and freezing point depresant. The water does all the work. If you are worried about freezing, run a 60/40 mix, if not 50/50, if worried about overheating run a 40/60 mix.
