So it is well known that the Trick Flow heads are great for the money. Does anybody run the suggested Trick Flow cam? I don't run that exact cam myself but the hyd roller cams in my cars are both similar. I do have a couple of customers who have used the Trick Flow cam. It makes good power but it is a little rougher idle than I prefer in a street car. I usually spread the lobes out to 112 for a street car rather than use the 108 centers. The Trick Flow cam can be tamed a bit if you use EFI (which I highly recommend) but even with a carb it would work. It will just be a little more "pro street" than I prefer but others might think it is perfect or even too tame as is.

Keep in mind the bigger the motor the better it is for the street. You can run a tighter converter and the motor will be more civil at 541 cubes than smaller. With a 541 a 3.23 or 3.55 is enough gear, and you can run a really tight converter for excelent street response.

So I see people suggesting to put together a smaller combo in a BBM.....505, 512, etc.....The 440Source kits for BBM's are the same price for the smaller kits to the biggest kits.....So a 440 block can go to 541, and a 400 block can go to 512....In a big B-body, the 400 based engine will look small in there. So go big and bring extra money for new rear tires! The 505/511 kits are just more user friendly. Usually fit without grinding other than the little notch off the oil pickup boss. And a TF 240 or 270 is still small for even a 505. I do agree a big b-body is heavy and can use some cubic inches. A 535 with TF 270s would be interesting though if someone else wants to try it. 😃 I don’t think you would go wrong with any of the kits for a mild combo.

Same here, love my 470 and with standard port intake runners and the right cam they run high and hard and are a blast on the street and track......

I am a big fan of the 470 combo on the street!
I run a 400 based 470 on 93 pump gas in my Belvedere. Small hydraulic roller, 440-1 heads, hooker headers, indy single 4 intake with a 4150 done up by Thumper.
Car has been 11.38 at 120 with a fully auto 727 (no manual valve body) and a turd of a converter. I drive this thing everywhere (been as far as a 2 hour round trip) and it is an awesome driver.
Just my two cents.
Casey FJ I may have asked before but what converter were you running and rear gear..... Thanks
71 demon stock stroke 440/indy ez-1 running 10.10 @ 132.14 mph in the 1/4 and 6.36 @ 107.46 mph in the 1/8 not in the same weekend but It did it then I sold it. 67 Belvedere that worked it's way in the 10's

The 270 heads could be used if a person wanted a little more top end power and was willing to give up a little on the bottom end. I have a B-body project in my shop right now that has a 505 with TF270 heads and a 260/266 street roller cam. That engine made right at 700 hp with 650 torque peak at 4900. That guy went with 4.10 gears which are aa good match for the 270 heads, but a little steep for freeway driving. Personally I lean towards the 240 heads with 3.50 gears but if a person wants to go with the extra spicy then 270 heads and 4.10 gears will fill the bill. I dont see any reason that the bigger ports would need that much more gear. My 500" pump gas motor was setup extremely mild just for street cruising, it had Eddy heads that were ported to max wedge size, I ran 10.69 at 124mph driving it to and from the track with 3.23 gears. These big motors don't need 4.10 gears in my opinion.

These big motors don't need 4.10 gears in my opinion. Well as an example we drive to and from the track and race in full street trim (3800lbs@line) with a mild 589ci 10:1CR motor 440-2 intake MW heads, small solid roller and carb, 2.1/8th>2.1/4" step TTI's, 29" tyres and 4.10 Dana. We trap@6200-ish, max power on our motor runs from 5500>5900rpm then tails off slightly and we have run 10.35@130 best and 1.43 60's to date. If we had 3.23's we'd trap@5000 with slip and have terrible 60's, it would be a total dog in my opinion even with our 700ftlbs+.

These big motors don't need 4.10 gears in my opinion. There’s reasons but I see your point for a street driver. In my case I’m doing a 511” tf 270. With a 4 speed I have to ride the clutch out too far with tall gears. For guys wanting the best launch a tall gear isn’t the answer, although usually 3:73-4:30 probably wouldn’t see much change. I do see your point as a tall gear is still going to et just fine and mph well. I believe Cab tried different gears with his stroked Duster? I could be wrong so don’t quote me. Maybe he’ll chime in.

I did try 3:73, 3:91, 4:10 and 4:30 in my old pump gas Duster, it went as fast with the 3:73 as it did with the 4:30 but I'm sure it was limited on fuel volume at that time. I did switch gears in another mid 14 second 4 speed Duster years ago from 3:55 to 4:89 that made that car FEEL a lot faster, it wasn't It ran 14:40 ET with the 3:55 and ran 14:20 with the 4:89 several weeks later, that was at the old LACR track in Palmdale, CA in the late summer going into Fall so the change in temps and humidity had to have some influence on those results BTW, that 4 speed car would bog that stock 360 motor with both gear ratios
