So I have been kicking around for years with my ebody and little J headed 340, asking questions on here and on the Moparts boards for the past 10 years. I've tossed around a big block swap, stroker motor, nitrous etc...to boost my power a little. When the Hellcat came out, I knew my high 12 second 340 wasn't gong to cut it anymore. I got a great deal on a set of ported W2 econo heads from a reputable builder on Moparts that flowed just a hair under 300cfm's at .600 and a ported Indy intake that combined with the heads, put his 2800lb A body into the mid 9's. That was going to be the end of it: slap them on my forged 340 with a nice cam, make 500+hp and call it a day, right? Then I realized I still had a practically new D1SC procharger and A1000 fuel system from a car I parted out...and I that same week I found a great deal on a D1SC bracket for an E body. Things got carried away fast.
Here's what I've got now. Should be picking up the motor from the machine shop either this weekend or next, and if the weather warms up a little bit (i'm working in a tent here in the North East) I may be able to get it all running within a month or two.
69 340 bored .030 over
Hughes stud girdle
69 factory forged crank
Eagle H beam rods
Speed Pro forged pistons, my machinist cut a dish into them to bring my C/R down to the low 9's
Iron ported econo heads with Mopar Performance shaft mounted rockers
242/246 @.050 112 LSA custom grind solid roller from comp, about .600 lift with the 1.6 rr's.
Ported Indy 360 intake
Ebay 3 core aluminum rad with dual electric fans
Fed by a trunk mounted 15 gallon fuel cell and Aeromotive A100 pump. 12 AN feed to pump, 10AN from pump to fuel pressure regulator, 10 AN split to dual 6AN from there to T/B
FITECH 1200 fuel injection throttle body
D1SC procharger on SDCE bracket using SDCE 8 rib crank pulley
Vortech MONDO bypass valve
Ebay 800hp rated front mount intercooler
8 3/4 rear with 3.91 gears and 1350 yoke (just swapped out the 4.56's, they were always way too much)
Pro Torque 9" converter ( was set up for my old small block planning for a 150 shot that never happened, going to try it out and see how it does)
TAC Trans 727
I will update with pics, some struggles I am running into, progress and hopefully in the not so distant future a dyno tune session.
I know some of the parts look expensive, but this is actually a VERY budget build. Many of the expensive parts I had lying around already like the procharger and fuel system or found good deals on used like the heads and intake. The only one part that was hard for me to drop the cash on was the FItech fuel injection as I knew I was going to pay full price, but the cost difference between that and a good blow through E85 carb was very slight and Fitech includes wideband. With this primarily being my street cruiser/weekend car, I think the fuel injection will be a very nice touch and I am looking forward to safer/more precise tuning (which is worth the money for me with the destructive power of boost).
I've been trying my best to NOT keep track, but I think taking into consideration the old parts I sold I will be about 8k into the build. I am shooting for around 650HP at the crank, pushing the stock block to the limits but trying to keep the RPM fairly low to make it last. I guess not a bad deal considering most guys I know making that kind of power have 8k tied up in their motor alone.
