What's the weak link in my 440 build?

I've been looking at some 29.5 street radials and either a 4.10 or 4.30 gear. I'll need to measure everything and make sure those tires will fit without too much work. I'm planning on moving the axle back a half inch or so. Hopefully that's enough. Also looking at Caltrac bars.

My mate mini tubbed the rear and also moved the Dana back 1" and this was a race only car. Going stroker is probably the only way your going to go 10 teens in that weight and keep it a street/strip car? which is what its going to be I think as you keep mentioning street radials. If your planning on using those tyres with a stick car that is a lethal combination for the street and will be a nightmare to get to hook@the track in my opinion made even worse with the extra torque of a stroker and if it hooks the rear won't last long if its an 8.3/4". You can drive it off the line and then hammer it but you'll lose ET defeating the whole $$ invested to get it in the teens. There are things like clutch tamers that would help but I would definitely put a pair of bias 10.5x28>29's slicks on the car@the track depending on gearing chosen and hope the rear lasts a while or go for a Dana.......You could of course keep it as it is now as a 440 which should be around the 540hp mark with the Stealths etc. without spending a whole load of $$$$ and put a small 125>150 N20 shot on it and achieve your goal that way leaving it on pump gas for the street.
