Andrews 54N Cams
Hello
Looking for some opinions on the above cams from people that have them or have dealt with them. To me (from the spec sheet) they look like a more gruntier cam than the 37N's. Looking at putting them in my new build as follows:
95" or 98" Big bore
10:25 SE cast pistons or equivalent CP forged pistons
R&R cast heads with comp releases to suit cam
Thanks for any input in advance

Have never built around the 54 but have around the 37. There is a saying about the 37............"the Andrews 37 may not be the right cam but it is never the wrong cam", not my words and don't remember where they came from but it stuck in my head. The 37's I have built around were both 95+HP/100+TQ.
Not sure the 54 is "gruntier" than the 37 with 4* later intake close and slightly longer duration but the dyno charts I have seen show broad and flat torque curves from the 54. Either will make a good runner, just set the engine up for the cam.
Don't know anything about the R&R heads but would have the stockers ported and machined for the cam selected in lieu of a "one size fits all" approach.

I have the 54 in a just under 10:1 105". Like djl said, the torque curve is broad and flat. I don't have a digital image of my sheet, but the torque jumps to 100 ft-lbs at 2700 rpm, peaks at 105 ft-lbs about 3500, and is very flat from start to finish. Doesn't drop off until right at 5000 rpm.

All in the setup and tune, both a little different but either would make a good runner.

Flat tops or the low dome 10.25 CR pistons; either willl work. Your head porter just needs to know which way you are going before he works the heads so he can set chamber volume.

You also can kick that cam(37) up, via 1.725 S/E non-roller rocker arms.
Boring to a 98", along with a head that'll flow 160-5 cfm @ 10".
A 51 HPI, with a 1.800" intake port may benefit as well.

How would that 1.725 SE rocker arm go in a 95" with SE flat tops, would I need to machine valve reliefs. & also how would the same rocker arm go with woods 6-6
