Those pictures look like a double notch,but what's the casting number on the back left hand side of the block? Is there a little X on the drivers side,front of the block? If it's a 62,it should have a 962 casting,if it has the x,you have one of the strongest,most desireable 348 blocks that there is.For some reason,:booboo:I thought that this was a 58-61 5011 truck block.

Alright, so I put alot of thought into this. The 0950 cam is just not gonna rock this thing like i want it to. So I have a blank blackboard. Goals are to keep the factory heads and run either the tripower or the 6 deuce setup with 94's and most important make this thing sound and run like a hot rod!!
Car is very light with a four speed. So game on... Do I work the heads and throw in a set of pistons or since I am in that far add more stroke!? Decisions Decisions:D

You will love the 0950 cam... My vehicle weighs 2600lbs and is a 4 speed too... running s*mbitch. It damn sure sounds like a hot rod.

When looking at pistons do I need to guesstimate a 2 point reduction in CR? With the block being notched and the 333 heads. I would like for this thing to land real close to 10:1

If you go the 380 route,get the 6.385 rod and the KB Icon piston[Show Cars pn 7815p plus oversize].This piston/rod/head will get you to right at 10-1.On the 333 head,install 2.06 intake,1.72 exhaust valves,bowl blend and clean up,port match,top it off with the 3-2's,and stuff in an 0953 cam,and HANG ON!!!!!!!!!!!!:chopper2: As far as the guessing about the C/R,figure about .3 compression drop between the 1147,,817 car heads and the 333 head.

That's exactly right,and that's why I recommend this set up.These pistons are about 200 per set cheaper than the standard Ross,400 if you get Ross's "maximum weight reduction" treatment that's needed to get them down to what the I cons weigh.Which side of the engine is your dipstick located?

Great,that means that you have the same basic thing as what came on the 409 car engines.The above mentioned "kit" will drop in,no issues at all.Post an add in the parts wanted section of this forum,cranks for the 09 are not hard to come by,nor are they expensive.

Took the little hot rod to the Drag strip yesterday. Glad I didn't line up against any Honda's. Cause I would of been embarrassed haha. I did baby it. The 4 speed is making a little noise and I did not want to bust it(have a spare going to swap it). 64 mph in the 1/8th ha! Hopefully the rebuild makes it more respectful!
