I would definitely be interested within a year from now. I will be doing air flow and retune (head work, intake work, throttle body, etc). Cams would definitely be on that list, along with whatever else in order to up the RPMs a bit.

No rollers used on direct actuated buckets. The buckets have what is about, I'd guess, in the neighborhood of a .005" crown. Not sure of that spec though.

id likely end up eating ramen for a few months over it

but id do it at around a grand, or a bit less, were slower than the v8's and we also outnumber those owners.

I would love to have some lope to the car!

I will most likely see boost before a 'built' motor, but it is still exciting to see options opening up for us. If they were affordable, and are applicable to different setups (na vs fi), then that is even better!

Please keep us updated on everything!

Are we talking N/A cams? FI cams? both? I'd likely be interested as long as the price isn't unreasonable. It would likely be a year or two down the road though... likely going to finish my intake and exhaust first. There's certainly nothing wrong with having more options.

Well, the LSA can be adjusted via VVT. ICL and ECL, obviously, can too but the trick will be keeping the int/exh duration increase modest because the further you go away from stock the more you're going to have to heavily rely on the tuner where some are not confidence inspiring with lesser mods. Cams only, maybe shoot for moving peak power up another 500rpms which should be able to be compensated for. The spring pressures would have to go up dramatically at that rpm but I also don't have an engine in front of me, with an engine dyno to figure these things out. That's the right way to do it and test longevity of the springs/ability to maintain psi as well.

Will the stock springs be up to the task of more lift?

Does anyone want to give a ballpark on the power increase we would have?

Streetable on a 3.7? I could go look at the current dyno graphs and visualize some typical graphs from v8's. Look at the gain's per 100rpm increment on an engine with good flowing heads for it's displacement, devide by 8 and multiply by 6....and STILL end up guessing.

My wild stab at it for a 3.7. 20rwhp with no porting to the heads. That will set what rpm the peak hp will be and from there you can make more on either side of peak with port work.

Just a suggestion if it hasn't already been discussed.

Oh....MORE than "just" enough spring pressure to get the job done too please. lol Like add 25lb to both seat and open pressure over what cam companies typically recommend. This accounts for loss of psi as miles are put on and the springs settle. This is a case where a little more is better than not enough or just enough.

I assume it'll be stock lift to keep it an easy swap without searching through several boxes of "bucket" to achieve the desired lash. Then there's installed height of the spring, stem protrusion of where the locks actually locate, etc. Just more aggressive ramps to get more duration under the lift curve?
Ha, you think the same way I do. Lift is being slightly increased, overlap moreso. Profiles being modded so as not to require tweaking of the cam tables in the ECU. Custom springs being made.

STMotorsports is looking at a complete kit for purchase. If you are in SoCal, they will install the kit. To include crank, pistons, rings, rods, heads, valves, valve springs, cams, etc., Damper Valve length on my engine is left oversize until cams are matched to heads, and valve stem can be machined to requirements.

Right now cam profile is being checked installed in heads, as valves were received this week. Preparation for master cam, hence the whole reason for this thread. If the article in MM and FF comes to fruition, lots of info will be provided.

I just got my personalized license plates SLEEPR 6. Can't wait to see this mustang on a dyno.
