My boss’s 40 coupe that’s been in “The Great American Race “ twice has a 3 5/16 x 4 1/4 ported. Cam. A single Stromberg 48 carb and runs like a raped ape. I personally have had it to 110mph with corrected speedo. At 65mph it sits you back in seat and keeps pulling. That was in high gear from 30mph. Was still pulling hard but I didn’t need a ticket. With his knowledge and recourses I believe this is fact that cubic inches matter. This just supports what I have personally found. |

I put a single carb on a 321 ci engine once just for fun and that thing would wheel stand if you blocked the back wheels. There are and always will be those that don't think the laws of physics apply to everything. |

Re: Relieved stroker motor with Ford aluminum heads
Ron, Many years ago I built a 296 flatty with OFFY alum heads, Almquist 3/4 cam, alum. flywheel, Jahns pistons, Crankshaft Co. stroker kit and then used a stock 2bbl 8BA carb. There was no noticeable performance difference. If you're going to be running a 2 barrel carb you will not see any difference in the performance of your engine, except that you will have bragging rights to having spent big bucks on performance goodies and big cubic inches. Just build a good dependable close to stock engine and you will be happier in the long run. Formulate a plan and then follow it.
REPLY: I was 23 and it was my first "hot rod" engine built from reading HOT ROD magazine. I can only surmise that didn't have sufficient knowledge as to what I was doing. Live and learn. Thanks for the replies. Jim |

Re: Relieved stroker motor with Ford aluminum heads
In this particular event, the cars with stroker motors are about 5 seconds faster than the stock motors. We have had both stock motors and modified versions alike , while i wouldn't say it makes a huge difference in feel , it does make a big difference on the time. We have changed the manifolds and added carbs and heads when running on the streets, and then as you say they come alive and all the work can then be felt in the seat. I understand the controversy and comments on class cheaters etc., that's just not what this class is about, its more about what you can do with a set of limitations than anything else. If you imagine what it was like street racing in the 50s and early 60s, you would be more in line with what its about. Its a event that happens once a year and has been going on for years. I am a little curious on distributer tricks if anyone has a little wisdom in that area. Drag racing tricks would be much more in line than circle track tricks.

Re: Relieved stroker motor with Ford aluminum heads
I guess your world is kind of like having 'restrictor plates' in Nascar . . . they just limit the amount of air that can get into the engine, limiting the total HP and resulting MPH. I'd still try to run a Big 97 at 250 CFM - with a hogged out manifold!

Re: Relieved stroker motor with Ford aluminum heads
Do you have to run a helmet style distributor? If so, make sure it has the 11A cam and advance mechanisms - will give you more advance (which is what you'll want). I'd surely mark TDC on the front pulley and achieve a total advance between 24 - 26 degrees all in. It is usually a bit easier to run a crab style distribuor - with the 11A mechanism, good points, etc - you should be able to handle 5500 - 6000 rpm.

Re: Relieved stroker motor with Ford aluminum heads
I have heard of it, but I never knew exactly where the "11A cam and advance mechanism" came from? I am assuming that it came out of a later style distributer?

It does 21 degrees or more with mods. It can be installed in an earlier housing. |

Re: Relieved stroker motor with Ford aluminum heads
I found this link to show you how to adjust the 11 A distributor , I thought it was pretty helpful. I have a sun machine and am currently looking for the adapter, I guess i can make it if I have to. i am hoping to find one that is reasonable If I can.
