Ditto, I`ve got a 440 in mine with 2" tubes, so I feel your pain, I`ve made dents in my $700.00 headers, however there`s a big payoff in the end .When these big blocks are tuned and ready in these little cars, there`s nothing like it! Don`t let clearance issues make you throw in the towel, remember Chrysler put HEMIS in these cars. :toothy7:
