4.10s or 4.56s

Saying it has a Lunati valve train doesn't mean squat. Lunati makes numerous cams, some are nearly stock and others wild solid rollers. Same goes for saying it has a high rise. What high rise???? A Edelbrock performer or a Super Victor, or??? Most all aftermarket intakes are high rises and each has a different rpm range. From now on if you want someone to guess what'll work give ALL the specs.

My vague guess is since you say it's mainly a 1/8th mile car I'd guess the 4.56's. But again without knowing what cam it has I have no idea on the rpm range so it's just a ballpark guess

Please don't take this as I'm being a smart ax. Think of it this way. What if I told you I have a 68 Cuda with a 408 and a big solid cam and a big 4 barrel and asked how quick do you think it'll be in the 1/4 mile with the info I gave you. See what I mean? You'd have no clue what it'd do cause I left so much out.
