Got a magnum out of a wrecked truck. 120,000 miles on it. Was originally thinking of heads, can, intake change. Now I'm wondering why not use the original heads. I saw where the engine came from. Truck wrecked and is now junk. Engine was obviously in running condition. I'm not saying I shouldn't look things over a bit.
From the research I have done on this site. It seems there are three heads people are using. Rhs, eq, and the edelbrocks. My thought is leaning towards the edelbrocks for two reasons. Smallest combustion chamber and they are aluminum. It seems by the time you get a 2.02 inch valve and the like. Your at the same price as the edsies. But stuck with iron heads and larger combustion chambers. It seems at that level they out flow the edelbrocks but again less compression and more weight.
It seems from reading the edelbrocks get hammered a lot about needing work out of the box. Then there is tons of people saying I have a pair and they have been fine out of the box.
I am leaving the short block alone. So changing pistons is out of the question. I am considering using the stock heads. Upgrading what I have to, to run the 380 horse can from Mopar or equevelent from a cam company. From researching here it sounds like molars crate 380 horse was making at least that. That's not bad. Especially if somehow I could wind up with 400 going that route. The negative thing I have been reading is they all crack. But it seems much of the cracks is not causing problems.
My goals are 12 second quarter mile times in a 69 valiant. I will be gearing the car based on the motor when its done. Converter to. I am trying to stay under three thousand on the motor from here. I have more if its really worth it.
So I'm open to input. Other than some reading here I don't know a lot. Being I'm never home. Over the road truck driver. I will be hiring my dad to do the engine work. He enjoys it. Has a nice shop. So I'm pretty lucky there. Just need to figure out what to get for this magnum. Oh yeah. The car will get driven a couple days a month. So gas mileage isn't a huge deal.
