11 second 440

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

Very well said Ron. Pretty much same thing here.

040 440, 10.5 comp, ported 452s (no flow numbers, but probably 250-260@ .600), M1 intake, 950HP,2 inch Hookers, 259/.550 Comp TL solid, 5k flash converter, 4.30 gear. 3800lbs, 11.3X's. With a 4k vert went 11.49.

Very nice combo on the street and runs find on pump fuel!!

My buddy's 70 RR ran 11.80's w/ a 10.5:1 .030 over 440, ported 915 heads (waaay before Eddy's) Stock 6-pack, MP 557, 1 7/8" headers 4 speed 4.10 dana.

My 74 cuda had a bone stock 440 with ol heavy trw2355 pistons. I put on a set of Indy Ez stock port heads, a hughes 576 solid cam, eddy victor Int with demon 850carb, Hooker comp headers with 3' exh. I run 3.91's and i have a 3500 tci stall. I know some of my parts could be improved on and i still manage a 7.25 in 1/8th.(mid 11's) Im convinced that 7.20 or better is in it. This with stock springs and 275/60 M/T ET streets. So i would say mid 11's are very easy with a stock stroke 440. Trick is the heads, cam, carb, stall, gears need to match up.

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.

Its a 4 speed car but I was using a 727 instead.

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...

here's what I have, very similar to what your doing, and i'll tell you my experiences.


i like to play at the roll bar rule, keep this in mind.

i have a best time of 11.63 @ 118.8 . average 11.7 to 11.8

i can run pump gas, but i do notice a performance difference. i usually blend 93 Sunoco with 114 and it's a little easier on the pocket. this is such a fun car to drive. ripping through the gears is awesome but the 4 speed is definitely the thing that's holding this car back. with an auto and the right converter, i could probably go 4-6 tenths faster. like everyone said, you will do better racing an auto over a 4 speed. the biggest problem is getting a good launch. it's just practice, practice, practice. don't expect to win a lot at first. i wanted the 4 speed over the auto though. for me, it's all about ripping through the gears. whether it's on the street or the track, i love doing it every time. and that's why i'll go a little slower over the auto. for others, it's all about the consistency and winning. i'm just out to have fun.

oh, about the roll bar rule thing. once you go faster than 11.50, there's a whole different set of rules you have to go by. i don't want to have to put the roll bar in my car and i like having the stock interior. the safety rules i agree with. i have good axles, bellhousing and a drivshaft loop. even with running in the 12's you gotta think safety too.

thanks for the help
i have a cope 727 & 3500 stall speed
going back to a 4 speed
just more fun
