I have the sum 6900Sorry, what cam do you have now?
So many pages.....
I actually like the Crane version best.
To each there own.
More compression for the 6901 ?? Or the 6900? Cause I have the 6900 I was just curious about the 6901.Check the Stan Weiss site for some flow comparisons
Back in the Day Crane bought Wolverine and a Big Detroit Camgrinder- which I think may have been in financial trouble
So Crane claimed that the ground all their cams "in house" ( that meant our in house Detroit not in house Florida) they were the supplier of the Summit cams and many others
we still need to get that dynamic compression analysis
summit 6900 closes the intake about 72 ABDC @.004 vs 6901 somewhere around 10 degrees later
so you better have lots of compression and still end up with not much lift or area under the curve
Wait! You’re worried about losing 4 hp on compression? I think you need your head examined. You’re splitting hairs, relax, just build the damn thing!Ok some good news I found a rear end and picked it up today so the 2.76 are gone!! That is gonna be a huge help! The rear end I got is a Ford 8.8 with limited slip 3.73! So I was doing some more number crunching.. Does any one know how much to is gained from a porting job on these 302 318 heads? I figured up if I used my felpro gaskets that I already have they are around. 054 the factory gaskets are .028 I will loose .5 cr which will be approximately 3.45 hp that is me not having to spend a dime on gaskets etc and doing home port job myself. Now granted I can spend 60 bucks and get a Mr gaskets. 027 and get it back but for budgets sake let's say I don't. I'm loosing 4 hp! Will I gain this hp and more back by porting or is it just gonna even itself out?
Lol not worried just weighing out my options. I tend to over think things. I was just thinking if the gains wouldnt be enough to cover that then would it be worth pulling the heads to port them? Your right I'm splitting hairs! Keep me straight rumble!! HahaWait! You’re worried about losing 4 hp on compression? I think you need your head examined.

i'll try in order....Ok some good news I found a rear end and picked it up today so the 2.76 are gone!! That is gonna be a huge help! The rear end I got is a Ford 8.8 with limited slip 3.73!

The purpose of my car is just a fun cruiser I'm not gonna be racing it I just want a street car that will have enough power to get me around and be fun to drive lay a black mark or two and not get out ran by a 91 Buick as someone here put it lol! Thanks for the input I'm just trying to get the best bang for my buck make it run better than stock without spending a fortune. Oh btw by cut do you mean mill? Or port? I wish I could find a new factory gasket loli'll try in order....
I forgot the purpose of your car, low E.T. or nice highway cruiser.... just back to thinking about your gears.....
- Going from 2.76 to 3.73 will be a huge help.... in the 1/4. Not for cruising on the highway, it will sound like your in 2nd gear.
- My average gain on "home-porting" heads is approx. 4 tenths
- Who said the factory tins are .028 thick? I'd say .018 is closer.
- Quit with your "paper" dyno. Cutting heads helps low end torque, so stop with the paper 4 hp thingy you got going on... LOL. That being said, I wouldn't cut the 302's.
cutting the heads means milling. My opinion, I would hate 3.73's if it spends some time on the highway unless you have Overdrive. Go out and put your car in 2nd gear and go 60 mph, because that is approx. what it will sound like going from 2.76 to 3.73's.The purpose of my car is just a fun cruiser I'm not gonna be racing it I just want a street car that will have enough power to get me around and be fun to drive lay a black mark or two and not get out ran by a 91 Buick as someone here put it lol!

Still you have a 278 @.004 seat timing cam with that Summit 6900
when you could have .461 lift at 264 degrees @.004 seat timing with a lot more area
I was thinking that myself. Is this thread still active? Has the OP installed a cam yet? @dartfreak75 , what's your plans? (save me the trouble of reading through 10 pages of chit chat)LMAO, tons of useless information there.
How about a post nutshelling it.
