narrowed down to 2 cam choices, convine me which to buy (solid or hyd) *DYNO SHEET*
Finally time to pick out a camshaft and I'm deciding between the comp cams 282S and XE274H
282S
dur 236 @.50 .578 lift with 1.72 rockers 110 lsa
XE274H
230/236 @.50 .558/.562 with 1.72 rockers 110lsa
With the solid i'd make some more top end and not die off so quickly, and have a better torque curve through the bottom end, but the only advantage I see of the hyd is better streetability.
this is going into a 351w with
forged pistons
ported/polished World Windsor cast heads
10.5:1 CR
vic JR intake
no carb yet, but probably a 750dp
150 cheater shot of spray
tremec 3550 5 speed trans
3.55 gears (i can see 4.10's in the future)
all going into a 2600 lb 67 mustang
I guess the basic question is the streetability difference between the solid and hyd. I want to drive this car as much as possible, but are the benefits of the hyd flat tappets on the street worth it to sacrifice the power potential of a solid flat tappet?
How many people have run solid flat tappets on the street? Not just to the track and back, but on a car that gets frequent street miles. How often do you check the valve lash?
Right now i'm leaning towards the solid 282s
I just punched all the specs for my motor in my desktop engine analyzer for a approximation dyno sheet.
green - hp of 282s
blue - torque of 282s
red - hp of XE274H
light blue - torque of XE274H
