I finally solved a rear main seal leak in my 512 after close to 1 years of replacing seals and main seal caps. I found that with my Milodon 7 quart pan if I went by my aftermarket dip stick I had close to a quart too much oil in the pan. After changing oil I measured close to 8 quarts drained...
I have a similar 512 with 270’s, 11.5 to one, 1.6 rockers, 4200 stall converter and 4.10 rear gear. I run a Indy single plane 4500 base with max wedge runners and a ProSystem 1100 cfm Dominator. Drive it on the street in the warm months. No real issues driving my set up on the street.
Indy had 4500 base, Max Wedge port single plane Low Deck manifolds in stock earlier this summer. Might be worth a call to see if they are still available. I also have a Trick Flow Track Heat 4150 base manifold that the runners have been opened up to fit 270's TF heads for Low Deck motor, I...
I broke in my Howards solid flat tappet cam last Spring by running it 3 10 minute intervals at 3000 rpm. Only additional precaution I took was breaking it in on just outer valve springs. After I had a couple hours of run time I installed the the inner springs that came on my Trick Flow 270's...
I have a FTI 9.5 SR Series Street-Strip converter behind my 512, it's advertised as a 3800 to 4000 stall but with my 512 it's closer to 4300 or 4400. The car sees limited use on the street but operates just fine and hits hard at the track while foot braking or using the trans-brake.
Don't use any 2 part epoxy without knowing it's heat tolerance, Most 2 part liquid base epoxies basically become goo above 400 degrees. The 2 part epoxy putties (in the tube) don't respond well to gas or oil, your high temp gasket sealer will take care of pits in the heads or manifold's...
I'm using a single line external oiling set up on my 512-400 stroker with a 21215 Milodon oil pump cover. In the Milodon single line kit that is back ordered from Milodon right now the 12an line is very short and runs in a straight line directly from oil pan to oil pump cover. Since I'm...
I'm in the middle of a 400-512 build, went with a 440 Source kit, .035 over, 11.5 CR which I can raise or lower the CR with thinner or thicker head gasket. 270 TF heads, I have 2 cams and haven't decided which cam set up I'll go with yet. One is a Howard's solid with 260, 264 duration and about...
Hang in there, Anyone that runs or owns a road bike knows you do your best thinking and problem solving on those long runs or rides. I'm sure things will work out.
I'm using a 440 Source valley pan and during normal use the pan stays pretty clean but on Wednesday night racing after 5 or 6 runs I'll get some oil puddling on the pan. I believe it's pushing up from the lifter valley at the 4 corners. Not enough grey ATV.
I had a set of E Streets on a 383 in a 66 B Body, only spark plug that was tight was number 6. Mopar electronic distributor fit fine with the Edelbrock heads. No issues, Mine made good power to 5800 rpm.
Comp Cams sells a couple different type of hydraulic lifters. One type is built to rev a little higher (500-1000 rpm) and requires adjustable rockers. This type of lifter is not to have any pre-load, just zero lash. The regular Comp Cams hydraulic lifters can be installed with factory rockers...
You will have to use a newer torque converter, Your 66 727 torque converter takes a 19 spline input shaft, 67 and newer 727 have 24 spline input shaft.
