I have a bunch of parts laying around and want to build a new motor for my 69 Road Runner. The car has a 4 speed (18 spline), Dana w/3.54 gears, and super stock springs. No power steering or power brakes, running radial tires. I have a 440 block, standard bore, but will need to be cleaned up, stock crank and rods. For heads, I have stock 915 closed chambers, 452 open chambers and a set of edelbrocks. All out of the box condition other than valve jobs on the iron heads. Is it possible to build a motor to get the car into the 11s without a stroker kit. I am running old TRWs with 12 to 1 now (I have some rod knock requiring an engine swap), and using a 6bbl setup with promax carbs. Car also has headers (not sure on tube size) and 2.5" exhaust all the way to the back. I built this motor 10 years ago using parts I bought 20 years ago.
My wife would like to keep the 6bbl, so I am sort of stuck there. I would like to go a little lower on compression ratio to be able to use 93 pump gas, but this isn't an absolute requiement. The only two pieces I am missing are the pistons and a cam. I do have, what I believe to be a MP 509 (old purchase from 15 years ago) cam sitting on the shelf, but haven't checked it out. I also am running a Crane 302H in the car now. Could I use either of these? I have some ideas, but looking for some folks who have used some current offerings.

GCH is correct. You arent going to get 11's without the Edelbrocks, unless you want to sacrifice something else. If it were me, I'd build a 493, have many of those customers combos out there and run easy 11's, but if you dont go that route, you can do it with the 440. The .509 wont get you into the 11's I dont think with your combo, again, at least not without making some other driveability changes.
Spend your money on some good pistons, quality machining, and you can get there.
Let me know if I can help.

I would run the Eddy heads and use a good flattop piston set at zero deck height. Use a .039 head gasket to get good quench and shoot for 10.5 to 10.8 comp and with the right cam it will run fine on 92 pump and get you in the 11's. That said I run iron factory 906 heads and use KB quench pad pistons to get 10.0 comp on the .030 over 440 in my 63. I use the MP solid .557 cam and a stock bottom end for the crank and rods. It has put my 3700 lb 63 in the mid 11's @ 116 so I see no reason if you build a 440 with Eddy heads and use a good cam like the MP .557 or even that one that you can get in the 11's with enough gear and converter. Good luck , Ron

Which KB's? The 236's?
I built a 446 with those and they are set at zero deck. The pad comes out of the hole... I didnt think it would run pump gas and iron heads.
Chris I did one years ago for a friend , 906's with KB's and an off the shelf cam and it ran fine on 93 octane with 38 degrees total timing . the quench needs to be right on though , I had that set up with .043-.045 , compression was about 10.3 .

Thanks for all the input. I will be looking at pistons this week. Unfortunately a stoker kit is out of the budget for now. Especially hard to justify a new crank and rods, when I have a new standard stroke crank and rods sitting ont he shelf. I like the idea about the exhaust cut outs. I'll see if I can some installed. I assume the Crane cam would be "too big" for this application? I don't recall the details on it. Just curious if its reusable.
I have also been thinking about going to 4.10 gears since I trailor the car to the nationals now. I trailer it so my wife and daughter can have some freedom while I scoot around in the car there.
