Shorty or LT's on a 289/302? Pros and cons for both please.

Longtubes will give you more torque, more hp, and overall are better for performance. Shorties are good for having clearance, if that is an issue, but I don't think they perform as well. Longtubes generally cost more if you are looking for ceramic coated too I think. I did see one dyno article where shorties gave a higher peak hp at the very top end, but torque was less. I would go with longtubes in an older car for sure, but that's me

Exact opposite opinion here: I will never go back to long tubes. They are a pain to install, most require a drop bracket for p.s., they hang too low, they are in the way, and the power is difference is simply not worth mentioning. Buy hi quality shorties, stage 8 locking bolts, and forget about them.

Stage 8's don't work for jack. I have them on my daily driver, they backed out. I have to retighten them ever 4-5 months.

Buy some mid-lengths. Check out Doug's headers. They are the new company Thorley started. I've heard nothing but good things about those.
