Hi guys, I havent been around for a while, been busy tooling with my 440 dart.
Got a few ?'s to ask. Im gonna build a new motor, for my dart. (too much time on my hands) I have the parts to build a 400 with a 440 crank. Is this a good power maker? I'm looking to run 11.50 or faster in the 1/4 and still be streetable. the car: 1969 dart gt, 727, 3500 stall, 8 3/4 with 3:91 rear Here's where i am at now, 72 400 block,70 440 crank turned down to 400 mains, 440 LY rods, .030 ross 10.50 pistons. Now i have a set of ported 915 heads but the the new MP aluminum heads really have got my gears turning. Not sure what I'll use yet. Now i dont know what cam and intake to use because i am not sure what the rpm range of the motor will be. any help will be great. I'm looking for the hostess with the mostest here. thanks guys |

Everything you have so far is great.You want a streetable ride.I'd use the heads you have now and a 292/509 cam.Intake- I'd try and find a old Edelbrock Torker 383 at a swap meet.The Mopar alum. heads are good,but need bowl work done first,otherwise they flow the same as a stock set of 906's- not worth the money in my book.The heads you have now can be opened up to 2.14I 1.81E valves and that will wake that stroker motor up.As far as what I said about a cam... I like a hydraulic cam for what you are doing with a set of Mopar Performance stock type rocker arms.It's easy to maintain and will rev to 6500 with a good gear in the back.Our 71 Demon has a 383 with 11.5 TRW's and the 284/484 hyd cam and it runs 11.60's all day long.I wouldn't use roller rockers,too much $$$.This motor should run 11.30's easily.
