Actually, that's astoundingly low considering the amount of women we have.

then there's those posts that don't have anything in them....

Flywheel. Desktop Dyno does not have provisions for calculating wheel hp and probably never will.

Theres a guy here that has one with a blower on a 350. Really nice.

HOLY F!

Yesterday I installed a new fuel filter and problem solved, it really came alive. I even lose traction after 5k.

Well at first I thought 400hp with those heads, compression ratio, and cam was waay too much. However, I'm sure you've seen the articles where this cam or something like it was swapped into a vortec engine (with roller cam and carb.) and made something to the tune of 400hp give or take. The fast burn heads I ASSume flow better than the vortecs so I guess that's possible. Your 8.5:1 might hurt you a little, however please let us know if it doesn't because I'm curious. BTW, Desktop Dyno gives you 349hp at 5k and 408tq at 3.5k with the exact setup you have including large tube headers.

Well there you have it as far as that idea. What I PREFER to do is get a late model block that already has a roller cam. You might see if a machine shop will take your block in as a trade.

I have seen this on ebay before and I would give it a try. I wouldn't do it on a high dollar engine but just to get a roller cam sure.

Will it start back up after it dies? If so it's more than likely the ignition module. Gotta hate 'em.

If I had to do mine over again I would build a 396 stroker. 13 extra cubes isn't going to do much for you maybe 15 hp but it should be comparable in price compared to a 383 and not many people have a 396 stroker. Atleast I've never seen one. As far as I know there isn't a major price difference between the 396 and the 383 is there?

Give us a good story grumpy. One where you don't have an excuse

My car started stalling out past 6500 when I put dual exhaust on it. I haven't tried to do anything about it but I guess I'll wait in line for someone to give us an idea what's wrong. I think mine might be that it's running too rich, but I don't know if that would make it stall. I don't crank mine past 6500 so it doesn't bother me too much, it kinda acts like a rev limiter.

He did?! Please point me to the thread if it exists.

I'm a pretty big advocate of vortec heads and not so much on the edelbrock performer heads. However, I wouldn't ditch the aluminum aftermarket heads for stock production iron heads. I don't think you will come out on top.

Look at JTR's transmission mount for the ZX, it is a three piece VERY adjustable mount that bolts onto the tunnel and everything is slotted. I have seen a mount that is just 4 bolts into the tunnel, two on each side welded together so that it's just one piece. The 4 bolt one is very simple and I would guess it would work fine.

I HAVE just tightened the crap out of them which will work after a few redoings but above is the correct way to do it.

haha, you thank the bank...

Don't take this as gospel but every tach I've ever had seems to be the green wire for the - side of the coil. ~Edit - Sorry I misread the whole post, however the same still remains, why not hook it straight up to the negative side of the coil?

Engine Name: 350 LM1 Horsepower: 249 HP @ 5,000 RPM Torque: 304 Ft/Lbs @ 3,500 RPM Compression Ratio: 8.50 to 1 Block: 4 – Bolt, 2 Piece Rear Seal, 4.000” Bore Crankshaft: Cast Nodular 3.480” Stroke Heads: Cast Iron, 76cc Valves: 1.940” / 1.500” Camshaft lift: 0.390” / 0.410” Hydraulic Duration @ 0.050”: 195° / 202° 249hp leaves much to be desired out of a 350. 304 ft/lbs is pretty weak too. You definitely want to get smaller combustion chambers to raise the compression probably 1 point (9.5:1) on an iron head. It's generally accepted that you can run 1 more point of compression with an aluminum head. You have a lot to gain starting off with a 76cc head. You will have to do the homework as far as how much which combustion chamber will do what unless someone else is kind enough to look it up for you. - As far as the rocker arms, the 1.5 and 1.6 is referring to the ratio that the rocker arm increases the lift of the cam. Say the cam has .200 lift, a 1.5:1 rocker arm will make the lift .300 at the valve. The 1.6:1 will give you .320 - My friend has the same engine and I have always tried to get him to turbocharge it or supercharge it because the compression is there and turbocharging it on your own would be somewhat comparable (pricewise) to new aluminum heads and cam. Just a thought. - Regardless, almost any modification will give you a lopey idle which is nothing to be ashamed of.

Junker Snowmobile huh, in Texas..... Have you been to Texas?... Any other ideas?!
