Looking for '49 wheat pennies Anybody have a pair they want to part with? Time to block those crossover passages. I'll use a different year than '49 but...well, you know

Re: Looking for '49 wheat pennies If you don't find any wheat pennies, Canadian pennies were 98% copper during these years. I think Canada stopped minting pennies a few years ago.
1982–1996 2.5 g 98% copper, 1.75% tin, 0.25% zinc 1980–1981 2.8 g 98% copper, 1.75% tin, 0.25% zinc There are 1949 Lincoln wheat pennies on Ebay. https://www.ebay.com/sch/i.html?_fro...penny&_sacat=0 |

If you are not worried about the engine swallowing the pennies and causing internal damage, by all means use them.
Otherwise all that I have ever done is bend up a thin piece of (tin can) sheet metal that can be slid in to install or removed if not wanted without removing intake. https://www.fordbarn.com/forum/attac...5&d=1640885710 |
Re: Looking for '49 wheat pennies Now there is a very good idea.

Re: Looking for '49 wheat pennies Copper- use a piece of copper plumbing pipe smash it flat, and cut out what you need. two thicknesses available at any store. Newc

Re: Looking for '49 wheat pennies I'm sure this question was asked many times, so what is the purpose of blocking off the crossovers? Less heat on the carb?
The pennies in the manifold reminded me of to two dimes under the bridge of my dad's fiddle. When asked why they were there, he would reply, "So I can say I'll never be broke." |

Re: Looking for '49 wheat pennies I know the "traditional" way to block off the heat risers was to use pennies corresponding to the year of the car. But, I liked '51 Merc's idea of a piece of sheet metal. I bought two cheap stainless putty knives at Harbor Freight and "sacrificed" the handles. Worked very well, more than covered the holes, and won't get sucked into the engine, being held in place by the intake manifold.
And....I really do like the way she raps through my dual Smithy's !!! (Have acknowledged that at my age, there's no hope of my outgrowing the love of a "modest" sound of power!!!):D |

Re: Looking for '49 wheat pennies I prefer a thin piece of stainless sheet metal - it won't rust out due to water vapor and other such fun . . .

Re: Looking for '49 wheat pennies The high zinc pennys were 1982 and after. Use any before then

Re: Looking for '49 wheat pennies Pennies won’t get sucked up, the holes are exhaust, not intake.
1/8” holes drilled in the Pennies keep the carb warm enough. I’d also be concerned about vacuum leak by using a stainless shim. |
Re: Looking for '49 wheat pennies I must have missed the part explaining why you would want to block those passages. I think cold performance would be better with that crossover working the way it was designed.

Re: Looking for '49 wheat pennies "RalphG", it sounds like you're one of "those guys" who think the Ford engineers knew what they were doing. I'm one as well.
I don't see why this is necessary except for an all-out race engine. The proper manifolds for those don't have a provision for manifold heat anyway, so why bother? |

It was a fad that intended to change the exhaust sound that some thought was "cool" |

On a more serious note, as cranky as a flat motor is (timing, carb adjustment, fuel distribution and engine temperature) the very last thing I would do is remove the heat under the carb for a "cool sound". |

Re: Looking for '49 wheat pennies I always used a stripe cut out of a tin beer can. You don,t have to remove the manifold just loosen the bolts, raise one side and then the other side and sllip them in. I all ways removed them in the winter time.........
