as ya knwo im puttin togather a 347 for my 88and i need help deciding on headers. the came with a set of MAC shorties, offroad H pipe and flowmaster mufflers, and custom tails. would long tubes be better for this application?

 

Absolutely! Its the only way I would go on your motor.

 

ok whats a good longtube for ths car?

 

bbk makes some nice ones! just make sure to get the mid pipe, or if you have a friend in the shop perhaps make some mid pipes, since the h-pipe you have won't fit with the longtubes.

 

Depends on the price range, Mac's are nice, so's the bbk and both are affordable. just know that the chrome plated will rust fast and the ceramic coated are more expensive but in my opinion worth it, they run cooler and look better longer. Borla and JBA are alot more money. Ford Motorsports long tubes are decent as well.

 

Oh just another thought, with your build you may consider going bigger than 1 5/8. you may get beeter results with 1 3/4

What heads and cam are you going to be running?

 

i plan on runnin AFR 185 heads and a custom cam. the macs i have now were chrome and they started to rust like ya said

 

Do you know what compression ratio your shooting for? those heads can certainly flow enuff to justify 1 3/4 headers. are you planing to spray the car or a sc in the future ?

 

the comp will be about 10.50 to 1 and i have considered maybe a 100 shot later on but that just a thought

 

You may want to consider the larger headers, it would be nice if someone else gave you an opinion on here. Isnt that why were here to help each other? If anyone wants to chime in and tell me i'm stupid he dont need them feel free. LOL
