Hi I'm new and need some good solid info without a lot of opinion.
I have a 64 dart 270 with a 225, offenhauser dual 1bbl intake with carter bbs I want to upgrade my exhaust manifold system. I have read all the post on this subject and I mean everything under headers, clifford, hooker, dutras etc.
My plan was to use the following, clifford headers-55-0010 Mopar High Starter Headers- with a y collector to a single pipe and muffler. I want to stick with the single exhaust and muffler set up just because.
The following are my concerns:
Regadingregardingds;
1-cliffords customer and quality service ( I am aware of the suggested ordering process)
2-the flanges not matching the flanges on the offenhauser. ( I have seen post with "they're perfect" to "they don't fit with out mods".
)3-coating not lasting, chrome and black
4-closing off the heat riser intake on the bottom of the offenhauser intake
Regarding dutras;
1- Starter clearence withoclearance I have the high,stock starter and don't want to switch to a mini)
2-heat riser connection mods without good core and clearence again
clearencen excess of $500) wow!
4- Whats the advantage to using only the front dual and then am I required to cut and modify the stock manifold?
5-closing off the heat riser intake on the bottom of the offenhauser intake if I use both duals without the core
Regarding Hookers;
1-The flange
2-bottom clearance ( I want to lower the front 1-1/2" to 2" with 14" wheels but slightly wider than stock)(front disc upgrade coming soon)
3-18 gauge steel vs. 16 gauge-interior rust from condensation?
4-coatings to prevent exterior rust
5-closing of the hear riser intake on the bottom of the offenhauser intake
Regarding MP headers
1-nobody seems to like these at all and they seem to need alot of mods
Can ana lot address these issues in a way that is less confusing than all the previous posts?
Thank you so much
Katrina
