Are those tunnel rams going to give the best low end response on a street driven motor with a couple of small carbs.? I'm looking into some W2 heads for my 340 and may be able to get a Mopar dual tunnel ram to go with them. Wouldn't be a max effort cam, need to be streetable with an automatic and PS/PB. Probably would go with a solid lifter. Should be a 10:1 engine if it's still got the original 1970 pistons, yet to be verified. Worth trying the tunnel or stick with a lower profile single or dual plane?
