360 Stroker Combo Build Questions
My '69 Dart came with a new 380HP 360 Mopar crate engine when I bought it a couple of years ago. I've been collecting parts since then and hope to get it together and on the road in 2010.
I planned on going through the crate motor anyway to verify all is to spec. Now I'm thinking of maybe a head change and possible stroker build using the same cam that came with the motor. From other threads I've seen the Mopar hydraulic roller cam was Mopar # P4876348. The Mopar advertised Duration is 288/292 with the .050-duration being 230/234. Lift is .501 on the Intake and .513 on the Exhaust using the stock 1.6 rockers. Center Line is 108 and Over Lap is 74-degrees.
Planning to use either 750 or 850 cfm annular vacuum secondary carb.
OK guys. Here's my questions for those of you with new batteries for your 'engine-build' crystal balls:
* What kind of HP/Torque numbers do you think if I may get if I go with a set of Indy MAX heads with 2.02-dia. intake valves and boost the compression to 10:1 from the existing 9:1?
* Go with the above heads and a 408ci stroker kit?
* Go with the above heads and a 426ci stroker kit?
* Go with the above heads and a 440ci stroker kit?
I know this is all 'crystal ball' guessing. Kinda looking for best bang for the buck. Car is going to be a weekend car with a trip to the strip maybe 2-3 times per year.
Other planned mods are 727 reverse manual shift trans, 8-3/4 Sure-Grip with either 3.91 or 4.10 gears with a gear-vendors overdrive for semi-comfortable freeway cruising.
Again, still in planning stages but only want to build one-time the right way.
Thanks for you input!!!
