Jay1970Z Posted May 24, 2002 Share Posted May 24, 2002 Ok, I hear you guys talking about "mild" V8 Z's a lot so what I'm wondering is what do you guys consider mild? Like how much hp are we talking here and what kind of performance would be your definition of a mild Z? Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted May 24, 2002 Share Posted May 24, 2002 a nice daily driver with just a little get-up-and-GO will only require 350hp-370hp, that will allow you to hold your own with most hot street cars includeing most stock vettes Quote Link to comment Share on other sites More sharing options...
Jay1970Z Posted May 24, 2002 Author Share Posted May 24, 2002 Will a stock Z be able to handle that kind of power, or will I need to weld on a subframe or something? I would imagine an engine with that kind of torque in a 240Z could do some damage without some sort of frame modification. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 24, 2002 Share Posted May 24, 2002 A car that is not rust damaged should take that kind of power (under 400 HP) but you will want a 200 rear end out of a 280 Z Quote Link to comment Share on other sites More sharing options...
Jay1970Z Posted May 24, 2002 Author Share Posted May 24, 2002 Thanks a lot guys, you are all so knowledgeable and helpful. I appreciate the replies and I think this site combined with the JTR book will make my V8 conversion a lot easier. You guys rock! Quote Link to comment Share on other sites More sharing options...
Guest kc6wfs Posted May 24, 2002 Share Posted May 24, 2002 Hi Jay, I may have one of the milder V8 350's. It's a Vortec 350 and had it on the dyno and only came in at 220RWHP. Also it has a 700R4 trans. Best 1/4 mile time is 13.307@101 so far. I have done a few changes since the last time I took it out.

Guest Drewz Posted May 24, 2002 Share Posted May 24, 2002 I agree with tomahawk that the original rust free z floor is pretty good for 350ish but if you intend of ever bumping that figure a subframe bolted or welded, prefer welded myself, is a very good idea. IMO! Quote Link to comment Share on other sites More sharing options...
Oltmann Posted May 24, 2002 Share Posted May 24, 2002 240z w/V8 2500lbs/370hp=6.76 2002 Z06 Corvette 3117lbs/405hp=7.70 I think 370hp would make for more than a mild Z. When people talk about mild they are usually talking about GM stock-replacement motors and junkyard motors (probably excluding the LS1.) 225-300hp.

Guest 1fastz Posted May 24, 2002 Share Posted May 24, 2002 350 horses ? to hold our own with most stock vettes? a properly converted 240z will weigh in around 2500-2600 pounds or 250 pounds LESS the the lightest late modle vetters. 500 pounds lighter then some of the heaveier ones.. a 300 horse motor in a z should hold its own with any vette.. 350 horses in a 2500 pound car = high 11 second quarter miles.

grumpyvette Posted May 24, 2002 Share Posted May 24, 2002 when I said 350-370hp I was talking about flywheel hp, thats about 285 rear wheel hp and most (z) cars Ive weighed are closer to 2800lb with driver and a full gas tank (still about 450-550lbs lighter than your average vette) Quote Link to comment Share on other sites More sharing options...
