1G Best cams for high comp stroker auto

[sleeper_pr]

Hi, i have a 1989 mirage auto Awd recently i upgrade my motor with higher compression pistons.
My mods:

100mm crankshaft
eagle rods
wiseco e85 10.5.1 pistons .40
gsc springs and retainers
port polish cyl head
jm fab intake manifold
injectors 2150
jm fab exhaust manifold
hx40 60mm bep .70
automagic build transmission
precision converter stall 4500


Im using HKS 272s cams but i was looking at the kelford 272/278 or gsc 274/274.
Need some help choosing the best cams for my set up and a vendor to get them.
Power goal is 650awhp.

Thanks.

I would wait to see how she stalls up before you swap to bigger cams.

The 272's should get you to your goals while still having decent vacuum in comparison to a high lift higher duration cam. I only got about 20-25AWHP changing to the equivilant to a 288* high lift cam on my 2.3L 9:1 GT4088R setup (740AWHP on 272's, 766AWPH on my bigger cams). I also had better mid-range on the 272's degreed in.

Also, be sure your valve springs are up to snuff; if you are running high boost levels make sure you aren't going to float.

I upgrade with some Gsc S2. Dyno results coming some time this next month.
