Will I get any gain with .120 crossover tubes? I dont know much about these but what will they affect if you dont have bigger lines? Thanx,

Paul

 

I've heard a truck with the bigger tubes in them. It idled very poorly. Unless your well over 700hp I don't see a need for them and even then I don't see a need for them. You can make 600+ on the stock tubes with ease.

 

I beleive Haisley says your truck won't idle with lines that big.

 

The tubes won't add any power. The big injector lines will cost you HP.....

 

I see that people drill them do they drill right through the little cross hair at the end or just up to it. I saw a set cheap so i figured I'd try them. You guys think it wouldnt idle? TIA,

Paul

 

Oh it'll idle. It'll sound like a big pulling truck but it'll idle.

 

I think it depends on the size. Here's your sign:
LINES AVAILABLE AND IN STOCK- .084 AND .093 FOR 12 OR 24 VALVE, .120 CAN BE ORDERED FOR THESE APPLICATIONS, NOT RECOMMENDED FOR THE 24 VALVE (ENGINE WILL NOT IDLE). CLAMPED TOGETHER AND READY TO GO!
