Hi guys,
I've searched the theads and found lots of information on how to build a monster 408 but I'm looking to build a solid, reliable 408 in the high 300 low 400 hp range. I wouldn't be stroking it except the deal I'm getting on the stroker kit is way too good to pass up. The car is a 72 dodge dart swinger with a 76 360 with in it. I don't remember the castings for the heads but I looked them up and they are nothing special. I currently have dougs headers, a standard performer intake, a holly street dominator 670 carb. and a full msd ignition. It's mated to a 904 built to handle 400 hp with a 2400 stall converter it's got a factory 8 3/4 posi in the back but I'm not sure what the gears are. I'm getting scat forged 4" crank, I beam rods, .30 over pistons (I'm told they'll give me 11.1 ratio on stock heads), bearings, hardware and gaskets. This is my first build ever but I am mechanical inclined and have tools at my disposal. I'm trying to do this project as inexpensively as possible but I also want to build it once and build it right. I am hoping to be under 3000 not including the stroker kit and components listed above.
My questions are
1) heads. Can I get away with freshening up the heads I have or do I need new ones? If so iron or aluminum and where would be my best bet on getting them?
2 ) cam. This is a street car, it's driven regularly and often by my girlfriend so I can't go to wild. I have the 2400 stall so I would like to take advantage of that.
3) carb. Will my 670 work if I adjust it or do I need to upsize? If so, what would be best? Again, it's a street car. I don't expect 20 mph but I don't want to burn my 12 gallon tank to go around the corner either.
4) like I said, this is my first ever build so I know I'm missing stuff, any advise at all is greatly appreciated.
Thanks in advance for all your help!
very respectfully,
JE
