I personally think with a heavier car as yours, I would guess a 505 on pump gas and some edelbrock rpm heads and around 250@050 or so solid lifter or roller cam and I think you would be there. Porting the heads would help too if low 11s are the goal. There's a big difference between high 11 and low 11s. I don't have any real world experience with the big block quite yet so this is all an educated guess.

I dont believe your setting your goals very high, I have a 67 A body that weighs 3200 w/me in it, and its old motor (last year) was running 11.50's with no problems. The 440 was a 68 block, 906 heads with small factory valves and slight gasket matching, .557 mopar cam, ductile rockers system, team g intake, 850 holley w/ a proform body, I believe the part # on the trw pistons were L2295s if I remeber correctly, wich were about 10.5 compression I think, on factory rods shifting at 5800rpm. My car has an automatic with a Coan 3500 streetable convertor, and a 8 3/4 w/35 splines and 4:10 gears... Pro parts headers into a full 3 1/2" magnaflow dual exhaust system, the car is a handfull on the street

As a point of reference, here's what can be done while being on a budget and still be completely streetable: '70 Barracuda that runs a cast crank 440 w/ 906 heads, 4.10 gears, 9.5" PTC converter, 850 AED Holley, M1 single plane, .588 Ultradyne solid flat tappet cam, 10.3:1 actual compression w/ Ross flat tops, Hooker Comp headers, TTI 3" X-pipe exhaust, 295/65 drag radials (or 275/60 ET Streets...runs the same) Not sure what the car weighs, but I assume around 3500 w/o driver. Full interior, all steel, heavy Magnum 500's, etc... In 100% street legal trim, runs 11.50's @ 118mph. Ideally, the car has 11.40's in it once I get the rear suspension sorted out. (One of these days...not a big priority honestly...just a fun car that is on the street much more than the strip.) With that said, 'streetable' has a different meaning to every person you ask. It's all in what the person can tolerate I guess. This burnout was a little overboard.

IMO,the engine will need usable low rpm power,like good power down to 2,000. With a 4spd.,and god I love`em the approach will not be identical to an auto. 1st issue is getting off the line. Either spin,lug the motor,or hook w/rpm`s and see what goes first-the car or the drivetrain. Your not going to get Automatic type 60fts. without lots of gear 4.88 or more and or a slipper type clutch{exspensive and not street freindly} So you will have to make up some of what you lost down track,which can work because a manual trans. is more efficient than an auto. When I went from auto to stick my MPH. went from 131mph to 135mph at the same E.T. Just sharing my expeirences. Can you do it ABSOLUTELY And it will be a blast to drive!

I run mid 11's with a mild 440 in my 63 but I agree a stroker is the easiest way to do it. Mine is a .030 over stock stroke 440 with stock crank and rods and KB quench pistons that gives me 10.0 comp and quench with my 906 heads I ported. I use the MP .557 cam and the Holley SD intake with an 850 DP. I run 1-3/4 hedman headers and 3" pipes. It runs fine on 92 pump and has run a best of 11.49 on a great day at 3700 lbs. My normal ets are 11.50's to 11.70's on average days. Whichever you build I would keep it simple and build a flattop piston zero deck eng with closed chamber heads and use a .039 head gasket for good quench. Good luck , Ron

The heads are out of the box.This car has full interor,10 point cage,and is all steel.Now that we have the shock's right it should run in the high 10's low 11's.It has 3 inch flowmasters on it,to the axle.We have driven it on the street.

My old combination went (in good air) 11.77 @ 115 in my 69 RR. It was a very mild, completely streetable, combination. I used to get almost 15mpg on the highway if I drove it gently. MP 484 hydraulic cam Stock E-heads 440 .030 over - stock lower end 10:1 Six pack with QF metering blocks 3:91s hooker super comps 1 7/8" Its a 4 speed car but I was using a 727 instead. tight 10" converter It ran great for years. I could drive it to the track, race, and drive home if I wanted. It would have been faster and less expensive with a single 4 and a Performer RPM. Eventually, one of the 40+ year old, stock rods failed and that was that...
