Hooray!

I just spent a ton of money to rebuild a 340 stocker with the LD340 intake to be somewhat competitive and to get a car back out to support NHRA class racing and this is the thanks we get in return. Thank you.

Send your "Thanks" to the folks at the NHRA Tech Dept.!!

If it makes you feel any better, according to a couple of Good Friends that race 340’s “ the LD 340 intake is NO better than the one I took off “.......

Hooray for some I guess. Might as well spread the joy. Original transmissions, original rearends, Roller rockers, Bee hive springs, 375/396 pistons. I'm sure the list could grow like wild fire.
I'm alright with the intake and it actual effected me personally. But try and remember that money was wasted here. As my Dad always told me. "If you have nothing good to say. Keep it to yourself."

How about all of the money that would have to be spent by all of the other Racers not running a 340 to keep up? NHRA made a mistake. They don't like admitting to their mistakes at the time that they are made. Thank them and send them the bill.

The Edelbrock RB4 AMC manifold also came with an AMC part number and it was also approved and later removed. As per the Mopar manifold, it was sold as an over the counter part.

Again It did effect me. So I guess I paid my share. Do I win a prize? Haven't seen many things get taken away like this. I guess Chrysler didn't have the check this box for Aluminum intake. I'll get over it. The folks that Billy said spent the money to keep up must be faster now and get to stay faster anyway. good for them. Sorry you spent money.

Opening a can of worms...

With the current camshafts in used, there is no way the valves will clear the piston dome. Many years ago, in the 1900's, a racer asked me to stop by his home to check why his new Crane Cams Stocker cam would not clear his pistons.
He believed he was doing something wrong. After checking the cam, the cam was not the problem; it was the piston domes. After making a few phone calls, I learned many were having their pistons flycut to be able to run the cams.
Having compared the current approved pistons versus the original, and they are very different. I assume someone may have sent a modified piston to NHRA to get approval of the alternate approved pistons.

Huh, that's weird, because a friend of mine used to run the approved TRW L2242F30 pistons with a Lunati stocker cam and no issues. This would have been back in the early to mid 1980's. They had unmodified top domes and his heads were the #840 castings IIRC.
