Look to the mercury 7.0 if you want to see where it woulda ended up. Sure wouldn't be ***** footing with 412-460hp and anemic tq

GM needs all the liters.
Sweet hypothetical racing tho!!
If Ford made a modern 427ci OHV design motor, it wouldn't drop valves and eat itself

NORTHSTAR was the pinnacle of actual GM designed DOHC motors those ******* things were less reliable than those MG Midget cars I'd count on a two legged horse to take me further than a NorthStar powered car.

Northstar is still the GM engineering pinnacle to this day.

TSP Torquer V2 (232/234 .600 112LSA) and if I remember right the current injectors are 26lb and new ones are 36lb at 43psi I think so with our rail pressure should be more than enough for what I've got. Plus a 100 dry shot is coming soon.

Call up FIC I've have some 60lbers from them lil Overkill but leaves some room for growth down the road.

Damn 60's give some room for sure, I've already got these 36lb waiting to go so might as well use them. Motor has 195K on it so I'm looking at short blocks now and would rather spend the money there first.

195k don't matter so much as the life it lived I've seen some 200k motors take a heavy shot and still live maintenance is key. Won't be suprised to see you get 230 out of it.

The funny part is gm's 4.6 made more power than furds 4.6.


Btw you can go over 100% duty cycle before the injectors go static.

The later designs were far superior and more reliable. For what it's worth, I put over 50K miles on a 98 Seville, once I did the timesert kit.

The L37 was 300/295, the B head 4.6L was 305/300. The LH2 was 320/315, the C head was 320/317. So when did the GM 4.6L beat the ford 4.6L?

Indeed, but they were supercharged 4.4L (not 4.6L) at 440hp and 470hp in the performance versions XLR-V and STS-V. Out-powered Ford's supercharged 4.6 though. They went with smaller bore size for increased cylinder wall strength, still the same motor. The N/A 4.6 Northstars were never rated higher than Ford's I think. But then again maybe the northstars weren't overrated like the early '96-'98 cobra 4v.

Muh bad....a lesser displacement northstar made more than the higher displacement furd.

All the na 4.6 furds were overated. But since the northstar was only a luxury car engine it was never pushed as a high performance engine as the 4.6 furd. So really the line linclon hp of the 4.6 would be a more accurate comparison.

Lh2 northstars were rated at 320hp. The northstars sounded incredible in the gtp cars they ran for a while.

Northstar makes more torque than the 4.6. 4.6 is gutless at low rpms

I have a lc3 setting around, I got it out of a wrecked xlr-v, less than 500 miles on it. I want to swap it in a new edge, but it's hard to find swap info on that engine though.

Northstars couldn't stay running for long enough to get those POS's out of the dealer's parking lot.

Nice runs. I always wondered how well an older ZR1 would run against something a little more modern. My neighbor (ex military; older guy) has one. I asked for a run but he is not into the street race thing. I know if I catch him out driving around though, he will get on it. They are impressive cars for sure but I think the biggest problems is getting parts for them (expensive) or finding someone who can still work on them. That is usually the topic of conversation when we shoot the ****.

They could run into the 12s stock. From what i have read it didn't take much to make them really get it on.

That was the 4.4L version and it made up to 469, but it was seriously overrated. The factory tune was a big problem with them. The tune was pretty much always the problem with the Northstar, back in the day, no one could deal with that complex Caddy system, the few aftermarket turbo cars had to piggback a different PCM.

Yes and no. The 4.4L had a higher "rating" than the terminator, but the terminator was underrated and the N* was badly overrated. On the dyno, the 4.4L actually put down around 350-360RWP where the Terminator put down right around 370-380RWP. I always preferred the N* powerband to the B head cars. I drove a 98 Seville SLS and my sister drove a 94 Lincoln Mark VIII. The mark was a tick quicker, but I did have the 270HP N*.
