hey jt69442, what grind is that cam?

[jt69442]

@pune51 its a comp cams extreme energy hydraulic roller 42-433-9 Duration 290/296, Lift .515/.533,

[jt69442]

this engine is only 9.5:1 compression very streetable never runs hot and tears the quarter up in a 3900lb car in 11.3

[jt69442]

The horsepower was estimated this engine with a 850 cfm Holley hp carb was acually dynoed at 575hp 613 ftlbs tq

I wish my alarm clock sounded like that

A 455 bored .40 over is 463 cubic inches you gain approximatly 2 cubic inches for every 10 thousands overbore.

The 455 Olds is a fairly available engine to find and even with a mild build will hit 500 ft lbs of torque at around 3500 RPM and maintains that to 5500 to 5800 RPM, It will move whatever its in fast if you can get that power to the ground without roasting your tires.

@jt69442 is that the advertised duration or the @.050"

Olds engines really like split pattern cams. I have an Erson Hi-Flow IIH in my 69 400 motor and the bottom is a little soft but when that thing hits 3500 rpm the tires can't hold it anymore. It pulls hard right up to 5800 rpm. The diameter of the rod journals is pretty large so there's a lot of bearing speed above 6200 rpm. Keep it below that and they'll take tons of abuse.

@VDragulaV I have that same grid cam man, look at my vid I just got her to turn over in the car... the vid is " 1974 oldsmobile cutlass 4-4-2"

[funguy7979]

well now I have to go and change my pants cause I just came in them.

[chuck2585]

are they flat top pistons or dished?

[dirtTdude]

what kind of olds might have hosted a 463?

[VDragulaV]

Hmmm I been trying to guesstimate what my car might run. I guesstimated my horsepower at 550 and torque to match. I to have a 463 1.25:1 but with a torker manifold. same 850 Holley but my cam is a lunati .539/.555 lift 284/292 duration and a 3680 lb car. So hopefully my HP TQ is higher than I estimated to and i estimated high 11's but was hoping at least 12's Which isn't bad for a STREET CAR. Gonna have to wait till next spring though to find out what she'll run.

Luv Olds Evey Sense Took A Ride in a 67 Cutless/331/4bbl motor It Never Seemed To Hit Top-end,It never Stopped pulling,We Quit Before That Mpotor Did Good Times

@eewood455 olds rev high too!so u get the low rpm torque and the high rpm hp!its the best of both worlds!
