Toyota I understand that its a budget deal, just trying to get you to understand the BIG difference between a VS and a DP with the motor spec you will have, even if it was a 750DP it would be much better, I'm not on about more cam/comp etc., thats a known fact, you don't have to have all that before you use a DP carb....I tried several VS type carbs on my 340 as an experiment, they were all flat out of the hole and lost me ET. As I said, run what you have, get some slips and then put a DP on and see the difference....all the best.
