Thank you Andy! Does it seem these combos have diminishing returns the bigger the camshaft you go? IMO, the "low" compression ratio (10-11) of some of these combos is not suited to 275 deg at 50 cams.

I'm following this thread closely. I am not touching anything on my TF240/10.6:1/solid flat tappet/3.54 geared street/strip car just yet, but I will be collecting parts to upgrade the top end after I get my Dart on the road.

Dont get sucked in to the 11to1 & up compression on a street car, just asking for trouble, I think I will keep my 9.7 & run whatever pump gas I want. No sense sitting on a knife edge waiting for detonation

No sense sitting on a knife edge waiting for detonation No worries. The chamber volume is the same, and I have a really thin Cometic gasket as it is. I think with the 270's and an intake to match and a solid roller I'd be up a significant amount of power. I want to beat on this combo for a bit.

The 270 heads will pick up power over the 240 heads but only if you use the extra air. So either more cubic inches or more RPM. You might need to go with 4.10 gears to use the extra volume of the 270 heads and then you'll have more of a strip car than a street car. Or stroke it and use the extra air feeding more inches.

It's a 512. More gear has been a thought, as well. But changing things is down the road a spell. I'm going to try to enjoy it for a few years.

A 512 with TF240 heads, modest cam and 3.54 gears seems like a great street combo to me. You probably have 600 ft-lbs of torque if you have a decent exhaust and the engine is tuned properly. I wouldn't be in a hurry to mess with that combo. Maybe get it on a chassis dyno sometime and see if you can tweak a little more power out of it. If it was mine I'd put a Sniper EFI kit on there rather than spend the money for 270 heads. With a Sniper you can dial the tune in and you can stay on top of it by watching the data logs. I posted my dyno session at the end of April. It made 491 at the tire. It's got 1 7/8 ttis and a 3" X-pipe exhaust with Ultra Flows. I'll be adding an AFR gauge when I get the exhaust tweaked how I want it. Efi might be down the road.

Mine is a 451 combo. 270 heads , 1.6 rockers , comp 707 solid roller ,12.6 compression , Indy 400-2 with 2" dominator adapter, 1050 , hooker 2" super comps . Haven't had the engine on a dyno . it did run some new bests last season. 10.14 @132 , 6.42@106 1.37 60' car is a hair over 3500 lbs. I'm guessing it might be 650 - 700hp so I would think a 511 should be able to make a bit more ! Nice, I've done a bit of a weird one here with an offset ground stroke of 3.800" x 4.350" bore for 452 cubes with a 7.1" rod. This is twin torqstorm deal and compression is a true 8.78-1. NA it made 612hp/545tq with a Comp RX296 solid roller. J.Rob

Our street/strip combo is a bit different. We are at 589ci, 4.565x4500, just 10:1CR which is not the way to go for the 365CC -13 heads, a tiny Herbert .625" 260/270@.050 solid roller, a 440-2 with a small older 950HP carb that pulled 2" of vacuum@max rpm and 2.1/8" step TTI's with 4" collector, dyno'd@ 695hp from 5500>5900 and 724ftlbs@4400, different animal to a 505/511 just another way to get 700hp which most wouldn't do but thats how it came all built and ready to go in for a good deal.
