Edelbrock Performer, LD4B, & SP2P-318 differance? - 06/04/08 03:58 AM
All three have the smaller 273-318 port size, so what are the differances in fuel economy between all three? Thanks.
Quote:Wrong!!! There is a vast performance difference between the Performer and the LD4B intakes. Noooo comparison.
the performer and the LD4B are basicly the same...

Quote:May be i s some aplications but for the most part will give very little over the OEM cast iron intake other than a huge weight savings.
you will see a gain over the stock manifold with a performer.

wrong...different plenum volume. different runners.

the ld340 is a good intake.

Looks good on paper but in the real world it has been proven again and again that they are little or no better than the cast intake in most cases. They work well as a cheap up grade to a 4 barrel for like we used to do on a lot of 318 trucks back in the 70's. Cheaper than the OEM manifolds and lighter. To each their own.

Wrong? Where did I say the plenums were the same? I said as compared to certain manifolds it was more like a stock unit.

mark7171 Well at any point are you going to reply...or do you save that only for an unwarranted attack where you still think you are correct?
