If the dragster is over 1950, most likely 7.50's will be your #. Under 1900, 7.40's is not a problem with the correct camshaft, intake and induction. If you are going to purchase heads, go with the 360, but if you have already spent the money, the 345's are fine. Just 900 hp will put you @ 7.55 @ 176-177. just 950 hp will put you @ 7.45 @ 179-180. Do it all the time. Gear and converter are more of an issue here.

the car was 1860 with my old motor alum headed filled block gear is a 4:10 16x33x15 tire (not sure how much the filled block adds?) thanks for your help i have 345 heads now but i have someone that will swap me for 360's

then your going the right way. The filled block weighs no more than a block with water in it????? People tend to think its heavier. The dart block is about 50 lbs + heavier. so your looking @ around 1925 and most likely 7.50's. Camshaft is killer with these engines.

I have our shelf grinds that work very well in that application. $399.00 for 7/4 swap, everywear gear and it will pull from 5000-7000rpm as good as any do. It won't kill the valve springs and has nice soft closings.
