[QUOTE="swampratt, post: 3102460, member: 15054"] I do like the hot rods and LS or old school small blocks or big blocks thrill me as long as they can deliver the goods. My old school heavy car with a 350 has bowl ported 305 heads and 268H cam 1.84-1.50 valves RPM intake and 750 carb. Iron ex manifolds Ported. It ran a best of 14.1 so far. I have 2 buddies with trucks that are within a couple hundred pounds of my vehicle one with a 5.3 with a different cam and LS6 springs with a tuned Holley injection system on it and another with an Escalade 6.0 with RPM intake and 750 carb .. both have headers and big short exhaust. I have 2.25" exhaust and full length out over the rear end. From a dead stop I will win in the 1/4 race. From a roll the 6.0 will pass me at 100 MPH the tuned cammed 5.3 will get me by 2 lengths by 90 MPH. Man the LS with it's aftermarket support is looking really good. BUT I just really like my old school stuff.. I am way down on power compared to these guys. But that is peak power.. I do not know about average. A few more tiny tweaks and I will be in the game but I trump them in the MPG department. My buddies 6.0 gets 9 MPG and I get 17-18 The tuned 5.3 made 330 HP at the wheels my 305 headed plugged up 350 made 247 at the wheels. Fun stuff. What do you guys like?? [/QUOTE]
