Need some advise on cylinder heads for my next engine build. The car is a 68 Charger, auto, 3:54 rear. I've been working on the car for about a year upgrading it to handle the more powerful engine. Chassis, brakes, cooling, rear, suspension, is complete and drivetrain is next. Transmission will be from Cope. Converter wont be picked until engine is run on he dyno. Engine will be 400 block with 440 source stroker kit. Final cubic inch should be about 512. A couple of things about the car: not a race car, 100% street. It will not hook up. I'm unwilling to cut the car for the appropriate suspension to make it hook up. Everything has to fit under the stock hood. That will restrict intake and I'm good with that. Finally, torque is more important than HP. Big engine is bragging rights and for fun. So that being said, Trick flow is at the top of the list. Which head would work better for this application: 240 or 270? Cam will be hydraulic roller. Secondly, knowing that this engine will make more useable power than really needed, would it better to go the Eddy heads? I have a 496 with Eddy heads (with some work done to them) and it's a hell of a fun car to drive. The engine will be professionally built and all necessary upgrades complied with. Is there another option? Finally, I don't mind paying more for better parts. Your thoughts? Frank

How is the ride with the Cal Tracs? That was on the list but I figured just go stock with a snubber. Have a SD on my 496 and hood just barely closes but that's a 440 block n96 car However you want it to be. The ride is more dependent upon the shocks and springs you have. I have mine set to where there's about a nickel width between the pivot and the spring. Some people add preload. My family rides in it and never has an issue.

1350 joints, u-bolts instead of bolts and straps for the rear yoke and good screw in studs for the rear axles are all going to be necessary if you have sticky tires and abuse it often. Trust me on this...
You said 3.54 gears so I'm assuming Dana 60?

400 block.......cant use the 440-2D ......... unless you’re running stage 6 heads.
Sounds like the OP has a good handle on what he wants.
None of the low deck manifolds that will fit the TF270 heads are really compatible with how the OP is describing the way the car will be used.
I’d suggest the 240 heads and an SD or RPM manifold.

I have a 400 stroked to 505 in my Challenger. TF 240 heads and TTI headers. I have a 2 inch scoop on my hood and I have a victor intake so that won't help you any. If you go with the TF heads just make sure you get the right rocker setup. I have the Harland Sharp set for Mopar heads but they are too long and don't hit the valve stem right. I have the HS set coming that are made for the TF heads. Was there any problem with the TTI fit on the 240? Is HS the only rockers for these heads or are they the best working rockers for these heads?

Head choice for a street car should take into account the exhaust system. If you are going to run headers then make sure you can find a set that works with the angle plugs. If you are going to use manifolds then you probably want to run a straight plug head.
I think the 240 head is the best choice for your engine if you can find a header that fits properly. You might be able to fit a 383 Performer RPM under the hood but you'll just have to check it.
Another way to go would be EFI. A throttle body is shorter than a carb so that might help with hood clearance. Also, the engine will run better with EFI and it will last longer. EFI........... Learn how to tune the "original" bad ass fuel/air metering manifold cooling device and you'll "get it"..........It's funny to me that you're suggesting/running EFI on your street cars after all of that max hp carb stuff you posted in your book and on here........

You might be able to fit a 383 Performer RPM under the hood but you'll just have to check it. i put a performer RPM manifold on my dads 69 charger with factory hood. aftermarket mild drop base air cleaner, 3" element i think. 906 heads, 383, holley 3310 and i think a .50" spacer. should be able to make a performer RPM fit unless the TF heads put the manifold in a different spot somehow..
