1.7 on HO Conversion? Reply #30 – August 30, 2008, 02:43:36 PM Quote from: Sick88Tbird;234131Actually you do NOT have flat tops...flat tops are just that...flat...no valve notches...go pull the heads off an '86 HO...now those are flat tops.I know *flat* tops have no notches. I've seen plenty of 86 HO pistons. My pistons (even though they have valve notches) are flat topped vs stock 87-93 HO pistons as those have a dish around the valves, where as mine do not.

Quote from: 1WLD BRD;234097I have pretty much the exact set up as Vinnie.... I dont think they would clear with a 1.7 RR....what Im wondering is.... Why are you bothering with the E6's to begin with? they are boat anchors... s em and go E7'sthe t-bird is going to be more then fast enough. im not going to try and make the cougar my hotrod, i dont want two money pits. i just want a little more power and i've done near everything a person can do to get power out of a SO motor, its time to go HO. im guessing 210hp now, figure cams good for 50hp, plus i have all new lifters pushrods and timing set. so 260ish maybe a touch more. not that bad.

If you're going to use it by it's self, then you'll be disappointed... If you plan on using the larger TB & EGR spacer, the 19lb inj, HO EEC and headers with true dual exhaust system, then you'll have the extra 50HP... With a true HO intake, and the 1.7s, probably closer to 60HP... Quote Selected
