Assume it has a cam matched with the rest of the components ?

Have you trailered the boat to a scale to see what it actually weighs as opposed to what it is supposed to weigh ?

Who built the motors ? I had Dart 345's on a 540 but with an M4 Procharger creating intake charge.

i have dart 345's on my 548. made night and day power over the gm performance heads i took off. way better mid range and 400 rpm on the top end. put some blowers on it and get that thing moving!!!

kellyO your boy cigrocket made a wise decision by heading south

Who built the motors ? Was it the builders recipe ?

a local establishment

Was it HTG Racing ? I have heard of more bad dealings with them lately. Don't know for sure if any of it's true...but people are starting to call them HTG....HOPE TO GOD....as in "hope to god it doesn't blow up"..."hope to god
I get my parts back"..."hope to god it doesn't take years to finish my motor"..."hope to god he used the parts he said he would".


Don't know if it's his workmanship or ethics...just saying whats being said out on the water by many lately.
