Im looking for input on what specs you would go with to obtain 550hp/600ft lbs (or thereabouts) to cruise-how would you build it specifically? I figure id get a built 727 as well. Who can build a turnkey 727 to handle that mild power? Just looking for input now to get it on paper and maybe tinker with it. Im tired of tinkering with the original drivetrain and piece-mealing stuff.

Eddy heads, old style Torker manifold (I had it), Holley 850 DP, Comp XS274S cam 236/242 @.050", .502"/.511" lift. Exhaust is 2" TTI's. The motor made 505 HP and 603TQ on the dyno. The transmission is a CRT "Pro Street" 727 with reverse manual VB. I highly recommend giving John Cope at CRT a call. You wont find a better person to deal with and this trans works great!

Anything different you would change if you had to do it again? Who built your motor? Did CRT?

Im tired of tinkering with the original drivetrain and piece-mealing stuff. I did a 505 BB using a Source 4.25 crank and a 440+.030 for a customer about a year ago using Stealth heads (I prefer Edelbrock)and a hyd. roller cam. It made 615TQ and 535HP and idled around 750-800rpm! Here's a link: https://board.moparts.org/ubbthreads/show...amp;Search=true Brian Hafliger

I have a motor like that getting ready to go to the dyno right now. 440 with 4.250 crank, ported Edelbrock heads, hyd roller camshaft, dual quad intake with twin 500 cfm carbs. This motor will be for sale once we finish dialing it in on the dyno.

Behind a big high torque 500 it would quiet things down, extend the life of your engine and save some fuel, especially if you will be getting out on the highway. A Gear Vendors behind a 727 or the Keisler OD automatic would fit the bill.

In terms of cost, by the time you buy a well built 727 plus the GV unit I'm not sure there is much difference. I went with a 5 speed Keisler manual behind a 550 ish HP 496 low deck. I love it.

Hydraulic roller cam in the 250 @ .050 range. 10.5:1 and it made 640 hp and 650 tq. Going into a challenger. I expect it'll make a great street motor. Power's all done by 6200 rpm.

If you go with the CNC ported version of the heads and step up a little in cam you should be able to do near 600hp.

The idea of the stroke is to make a torque monster streeter that can pull hard with say 3.23 or 2.94 gears. It works for me with my 471 incher and 3.23 gears anyway. I've thought of changing to 2 series gears but the car cruises great at 80-90 MPH with the 3.23's and I need my driver's license. Sheldon 5632426-66coronet3.jpg (142 downloads)
