I race Dirt Pure Stocks, currently racing a 79 Firebird with a Chevy 350. The tech's are harassing me about the placement of the engine and are saying that my engine sits too far back. I am using factory Pontiac motor mounts. I've been told when using a Chevy engine in a Pontiac, the engine will be lowered 1" as well as moved back 1", which will replicate the engine position of a Camaro. Is this true?
Normally the rules say that the #1 spark plug cannot be past the upper ball joint. This track, the rules are very vague. The tech is going by the location of the fuel pump and says the fuel pump should be one and a quarter inch ahead from where its sitting now. The same tech also said he supposedly went out to his barn to look at his 71 Camaro to specifically look at the location of the fuel pump and that his 71 Camaro's engine sits further ahead. Im sure the difference in years between his Camaro and my Firebird alone are enough to void that judgement.
I'm hoping some of you can get me some pictures of your fuel pump in relation to the upper control arm area. My fuel pump is almost touching my control arm. I am also looking for some concrete proof to take with me to the track that my engine is sitting in stock location. It's going to be a huge inconvenience if we have to move this engine. We will probably have complications with the driveshaft and transmission mount (it lines up perfectly the way it sits in the car now). Not to mention we will need to adjust our clutch, throttle, and shift linkages.
We are running cast exhaust manifolds compared to the other cars with headers. We have a stock intake manifold, they have aluminum intakes. We are running legit mufflers, they are not. We are using legit street tires, they are softening their tires. Whatever advantage I may have on the other cars as far as engine placement goes, it's not going to matter. The car count for this class is also very low. The first week I went, there were 7 cars. Last week, there were 4 cars. I really don't understand why they are picking on us when there are only 4 cars. This week, I am taking my American Racers and if they have a problem with it, I will race with the Street Stocks that consist of well over 20 cars while the Pure Stocks will only have 3 if I do switch.
