Need some advice on choosing an engine

For a street/strip toy I'd do a low deck stroker(470-500"). With the RMS sub frame and some aluminum engine pieces(heads,intake,wp housing,etc)the weight difference is a non-topic. You won't need to have huge squeeze and big cam or spin it hard to make your goal which will improve streetablility. 10.5:1 and a good solid roller with a decent head and converter and it'll be a handful of fun! Sounds like a great build...keep us posted!!
