I need some help with some lsx block decisions. Id like to build a carbureted lsx to take the place of my sick 350. What all strokes are available up to 4.50". I'd like to do a 4.00" x 4.00" for a 400

We build a lot of the 4.030 x 4.00 408 stroker motors. They have been very popular and reliable motors over the years. We offer stroker rotating assemblies as well as built short blocks, just depends what you are looking for. If you have questions feel free to call us or send me a PM!

go to TSP web store ,they have too many combos to choose from.do a 402 or bigger with a ls3 top end.

If I go with the 408 which heads would be best?

what can you afford ?how much power do you want to make ?the bigger the valves the better.you can get stock gm ls3 heads for $325 each,or get ported ones that will make more power.
