what do you guys think of this cam in a 377C 4V quench with 11.5 max comp, i say max cuz i dont know exactly if i will get some parts that will yield 11.5.Crane cam part number 524551 Series number: Commander CCH-294-2-NC Power range: 3000 to 6000 [email protected]: 224_int / 234_ex Adv. Duration: 294_int / 304_ex Gross Valve Lift: .535_int / .562_ex they dont specify the lsa.
forgot to say its hydraulic.
this car is gonna be a daily driver 80% of the time. what would be a good performance cam? i think i know i have to use octane booster or higher octane fuel. Aldo [This message has been edited by '69PonyRider (edited 11-12-2003).]

cut the compression down, or put it higher aaand call it a race car. with 10:1 motor or less that cam would be fine on the street i guess. lobe sep. angle is a huge factor not listed. if its a racecar, that cam is way too mild. 11.5 comp. in my view is not what to shoot for. maybe im wrong but if you are gonna make a motor that has to have race gas then dont screw around with 11.5 compression. ------------------

I don't like big hydraulic cams at all. Loose too much torque down low. Go solid or stay on the porch!  ------------------

I don't like hydro cams at all in clevelands. I don't like leaving the oiling system un restricted and pumping that much oil to the top of the motor, which does happen whne the rpms go up. As for the compression, nothing wrong with 11.5-1. Too many people get hung up on numbers, and not on the reality of chamber efficiency. My last motor, which was 11.5-1, ran 6.18 in the 1/8, a full tenth faster than the previous motor which was 13.85-1.
If you use flat tops, zero deck the block, and end up with 11, or 11.5-1, it should run on pump gas. So long as you don't get carried away with your timing, or put a really small cam in it.

Beware too of this cam, the specs are wrong with the part number you listed. Lift 536/545, dur @.050 230/234, this is what the cam really is (writing this as I look at my cam sheet). I know because this is my current cam and I am looking to upgrade. I am in no position to give an opinion, I am getting ones on here like you. ------------------

Kid,will a little dome on the pistons affect chamber efficiency or performance overall? i will be using the 4V closed chamber. Aldo

Yes, any dome effects the efficiency of the chamber. However, the bigger the dome, the worse it is. That's why all the NASCAR heads have little itty bitty chambers. Before the rules mandated a certain compression ratio, they used to get as much as possible while using flat tops. Anyways, you shouldn't need any dome if you stroke it. With a 64 cc head, the piston .005 in the hole, a typical Felpro 1013 head gasket and flat tops, it comes out to around 10.9-1 compression. That's plenty for a street motor.

i think you better have a cam with enough overlap to bleed off that cylinder pressure with pump gas on an 11:1 motor. run an aluminum head and keep it under 11 to 1 and you should be good. ive seen some engine builders like joe sherman build these high compression motors that run on pump gas but they have access to a lot more toys to do this than the shadetrees like us. ------------------

Chip, I tend to disagree with you on the need for "a cam with enough overlap to bleed off that cylinder pressure with pump gas on an 11:1 motor". The 351C-4V in my 70 Torino GT is a factory 11:1 (advertised) motor and has never had a problem with detonation on pump gas. I read somewhere that the 351C has the best quench design and is not as prone to detonation as other engines. ------------------

based on what ive read and heard from the machine shop today, ive decided to go with an 11:1 351 4V, now what would be the ideal cam for this engine? I would not mind a "lumpy" cam, and needs to run on pump gas.Aldo

I Disagree. I went from a 108 CL that had to have additives to a 110 CL that runs on 91 pump gas right now. Also note the duration went from 224 @ .050 to 244 @ .050 as well...
