Stock 1975 Dodge Coronet. Mopar guys.

[383bigblock]

Thank you everybody for the replies and insight. As this would be my first experience with NHRA stock along with a couple of friends and we have a 1975 Coronet with a 400 it seems that if we went this route it would be a learning experience and wouldn't be competitive on a national level and/or in a heads up situation, not that we're expecting that. Might it be at least a consistent combination with either the 400 or 360?

Consistency depends on how you build it, tune it and know what to expect from it under different conditions. "Predictability" is the key. Weather stations/predictors can help.

As for competitiveness, if you get the previously mentioned factors figured out AND you can at least run under the index in the worst conditions and have decent reaction times, you are, for the most part, competitive! Class eliminations or the occasional heads-up in regular eliminations are another story. That's where finding the most advantageous combo and a lot of work and resources ($$$) to be among the fastest comes into play. A specific class with the least amount of cars competing in it can be helpful in avoiding heads-up runs while you make progress on yours. You can move up or down one class from your "natural" class with weight.

Thank you for the insight Myron. A couple general questions. The technical specs for acceptable carburetors shows Carter Thermoquad
9008,9054, 90064 and 9097. Just to clarify these are the numbers that have to be stamped somewhere onto the carb correct? Engine blocks?
Any year 400 block is acceptable?

[Myron Piatek]

Any year block and any TQ with the same venturi & throttle bores. No machining and the choke parts stay in place.

Thank you for the replies. West coast guy here. Who are the mopar guys to deal with for engine machining/building? Ive heard different names over the years just not sure who is still around for stock engine builds. 727 OR 904 behind a 400ci stocker? 8 3/4 or dana? Thank you.

Our 400 Mopar short blocks was built by Gregg Luneauk at Tri City
Performance in Vista Cal. It is 1 Second ++ when we need it to be!

Must run 727 as 904 will not bolt in without Illegal Adapter.
Pro Trans in Waco Texas did the Transmission.

We break a lot of very good 8 3/4 in that heavy a car. 73 Roadrunner @ 3800 Lbs
