Default Best engine combo for 2008?

Hello AS Drivers!
I've missed a season and a half due to some injuries but I am hopping to be back this spring. I've noticed quite a few engine rule changes. I'm currently running a 1998 Mustang with a 302 engine. Now it looks like I can go to a 358 engine, add 300lbs or stay with the 302 and deduct 100 lbs. Considering the large amount of head, engine block, crank shaft, connecting rod, piston, etc. combinations, not to mention a 400 lb range of car weight, the correct selection seems pretty broad (of course the GM drivers are faced with the same task).
If anyone has suggestions I would greatly appreciate it. Thanks for the help and happy racing.

My suggestion is to run what you currently have and see how it all flushes out. Get some much needed seat time since your injury, evaluate your options in a year or so.

Tom,
Good question. I'm running last year's engine, but will try to have something new by the end of the season. The new heads will change the equation, so I'm not committing until that issue is settled, once and for all. I don't know what guys like Andy, (or anyone else) are going to do. I'm not real sure anyone knows yet.

Shifting Gears on Racinboys.com, starts its second season on Wed the 9th at 7 p.m. central. Call in number is 888-883-6363 toll free. We are going to try to address more issues from anyone that has an opinion about anything going on in SCCA. Road Race, Pro racing, solo, rally cross, whatever.

The word I got was that the Fords were restricted to a max displacement of 347. As in a stroked 302. 351's are not legal.

Incorrect. Jan. FastTrack max bore 4.040", max stroke 3.500", 8 cylinders.
Just don't forget about the weight penalty if you run over 313CI.

I beg your pardon, good sir. The email I recieved from an ADHOC member was that the Ford 351 would be illegal.

Robert,

Per the current rules that are recently approved at the Board Of Director level, the ford block has to have the deck height of 8.188" - 8.224". This is a 302 block, so the 351 blocks are not classified, and therefore not allowed.

The bump in displacement is allowed, however, by making a stroker from the commonly available stroker kits.

Additionally, the only approved intake manifold will not bolt up to the 351w block.

So, to build your car to the current rules, you have to work from the 302 platform.

To get this rule changed, you need to write a letter to the CRB (Competition Rule Board). The way the system works, there is an ASedan Advisory committee (The ADHOC), which is directed by the CRB to evaluate the merits of letters requesting change. Once we have weighed in, the CRB has the power to make specification adjustments, but they must forward a rule change up the ladder to the Board of Directors, where it gets voted in or out.

From the ADHOC point of view, we talked about this block, but eventually when weighing the argument from many perspectives, including Chevy guys and tech guys, we have settled on one block size for each car. The Chevy situation is a natural, but the ford situation requires a stroker kit, but they are common and reliable.

Thanks,
(name witheld to protect the innocent)

If this has changed, however, this greatly improves my engine program...
