Re: Super stock e7te ford heads

The E7's I ported I used 1.84/1.50 valves. I feel it gave a better shape to the SSR on the intake. There is not enough material there to lay the turn back to get a good shape with the 1.94's. There is a good thread here on porting them somewhere. I used some of the info there to do the set I worked ...

Re: Flat Tappet vs Roller Specs

The specs are telling you when the valve is opening and how far. If you had the exact same specs in a roller grind the shape of the cam would be different because of the round roller lifter nose, but the valve should open at the same time and same amount. Some roller grinds cannot be achieved with f...

Sounds like Manley's quality control department needs to step up.

Re: SADI cam core

I chose the Erson spring because it will use the same locator and retainer as a PAC 1243 and install at the same 1.900" height. If down the road the guy decides to swap to a better camshaft he could just pop in the PAC springs and be good to go. I have had good luck with the Erson 3850's on my own c...

SADI cam core

I am working on a set of heads for a Windsor ford build. The engine has a Comp Xtreme energy solid roller camshaft. How much spring load can this type of cam core handle? Comp recommends thier 954-16 and it says 210 seat at a 483 spring rate. The camshaft has .621 lift. At first I was going to use a...

Re: 327 Build

Have you looked at any of the street solid rollers? Some of the more mild stuff you don't need a ton of spring pressure and a good set of lifters would last a long time. The solid roller lifters are usually cheaper than hydraulic ones and can be less fussy in my opinion. You hear of some unhappy peo...

The tech was probably not giving you bad advice then. If its a daily driver, thats completely different than an occasional cruiser.

Re: BBC pro dominater tr

Is this street driven? If it is I think the duration is ballpark, a lobe with more lift would help it some. Maybe you got the wrong tech at comp cams.

That could use some lift... Any way you could get some 1.8 rockers?

Re: Solid roller wheel size

If you can afford the bigger wheel... Get the bigger wheel. It has a larger axle diameter and more bearings which increase the capacity of the lifter.

Your pistons will not work. The rods may be able to be used over with the new crank if you get pistons that will match.

Re: Cylinder head CFM to HP?

Re the 2 HP per CFM "rule of thumb"... you know what it's still good for? If someone says they're going to build a 700 HP NA engine with 280 CFM heads, I know they probably "can't get there from here", unless we're talking about a high-end engine development program. And when I see someone builds a ...
