Fcam on a 351. The higher displacement makes the cam milder. Def do the dual plane intake and you will need valve springs. Take it from a modded 95 Lightning owner.

It's pointless for yourself and myself to argue about a discipline neither has competed in. I'm going to trust the high level competitors whom regularly post in the road race/autocross threads on this site.

If you scale a power band between 2500 RPM to 6500 RPM, that equates to 3500 to 9100 RPM, even if you make enough torque at 3K to accelerate well out of a tight 180, that scales to a top end of 7800 RPM. I would suggest that is unreasonable for the average competitor, serious valvetrain componentry, and high maintenance. But I'm glad you got your opinion out there, not good to stifle one's very own self! (y)

The only point I was making is about power band and the RPM that can be used. I would need a lot of teaching on how to most efficiently drive one of these courses. The principle of how much power you make with a certain displacement and the appropriate gear associated with a higher RPM range just makes sense for all out acceleration out of the corners and in the straights.

Definitely not budget friendly! Good chatting with you. 馃憤

Just to let you know I have won 3 SCCA season championships in SOLO 2 (Autocross) So I have a pretty good idea of what works and what does not.
This motor that I asked about is only a place holder as I accumulate the rest of the parts for my long term engine.
All of my experience has been with 302-306 ci engines, so I was just seeing if anyone had more experience than I do when it comes to a 351w mild combo.
My gut feeling is the Performer RPM, intake with the E303 cam, however if someone here has tried that combo and had feed back it would be great.
And yes, if a car is set up properly you will run most tracks in a single gear, depending on engine operating range and transmission it is normally between a 3.25 and 3.75 ratio.
Great job on the championships. With the cam you鈥檙e talking about there is absolutely no doubt the dual plane will work best for you. I was just rambling off about the hypothetical advantages and disadvantages associated with an RPM range .

I think that cam and intake is suited for a pick up
truck. Towing a car trailer. But that's just me

If there is a tire rule and it鈥檚 being run in parking lots and airstrips it鈥檚 traction limited and now makes a whole lot more sense to me. I鈥檓 the guy who hit a home run ten feet over the fence but was mad I didn鈥檛 hit it fifty feet over. Why use a a screw driver when a hammer will work. Sounds like a whole lot of fun and a very disciplined skill. Never mind me. 馃憤

If you ever get a chance get out and try it, regardless if your car is set up for it or not you will have a blast!

I snuck on that form and a couple minutes of reading revealed a lot. I鈥檓 a fan and could swap my GT 350 style suspension back into the car. Original plan was Willow springs. Then I went drag racing with a buddy. I love what you guys are doing. More power to ya!

I regularly watch the Optima street car challenge on TV, some of the best of the best compete in this series. These competitions always include an autocross, one of the most difficult competitions IMHO, and very entertaining.

Exactly. Ultimate streetcar challenge type of stuff.馃憤

I think I'd go with the Fcam, 1.7 rockers, the dual plane and as big a carb spacer will fit under the hood.

I'm totally open to buying a new cam but just really want whatever cam I go with to work with my steel distributor gear
Would it be worth the extra expense to have a custom cam (and probably springs as well) in this particular "place holder" engine? I'm sure you could do better than the alphabet cams as, no doubt, you must also be aware. I'm just not sure how much difference it would make, and how long this engine will be in the car. I realize no one knows how long before certain parts start to show up, it would be unfortunate to spend good money on this temporary engine and then yank it a couple events into the season. Some judgment, some guesswork.

I've been watching some of this builder's videos, he specs custom cams and he actually lists his phone number on the web site, so you can call and talk to the guy. Ford specialist, decades of experience.
