Through the years...

127-130 MPH in my 1970 Z-28 in 1981

150 in Hassett's 1994 Supercharged Z-28 in 1997 (Fried the computer on that run)

North of 165 in a Dodge Challenger HellCat in 2015

Some time in the late 1980's if memory serves me;

My street toy at the time was a 1975 Monza hatchback. Under the hood was an 11-1 355 with an Erson 320HLM solid lifter cam (250°/250° @ .050&quot;, 320°/320° adv. .534&quot;/.534&quot; lift on a 108° LSA), a pair of 370 casting double hump heads, and old style Edelbrock Torker intake (looked a lot like the Scorpion) and a 780 Holley and a pair of Hooker headers.

Behind this was a Turbo 350 with a Vega converter and a stock 7.5&quot; rear end with a posi and 2.91 gears. Don't let the gearing # throw you off, the tires on the car were only 24&quot; tall (13&quot; rims after all). For reference--it turned ~2500 RPM @ 60 mph.

I beat that thing like I hated it--turned it 7500+ rpm on a daily basis and topped 8K on the Sun Super Tach II on more than one occasion. [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

One night a friend and I were coming back from &quot;cruising the circle&quot; in Greenville, which was a town about 30 miles North of me. Access to Greenville was via a State route which is straight as piss and has several lengthy sections with nothing but fields on either side. You should get where I'm going with this...

Long story short, I turned the car loose and let it eat. The car had a 120 mph speedometer which was buried well before I lifted...(I don't know who GM was trying to kid with that--the OE 262 in the car was lucky to keep up with traffic! [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img] ) When I lifted, the tach was just nosing past 6800 RPM and was still rapidly climbing.

MPH X rear gear X 336 / tire height = rpm

155 MPH X 2.91 X 336 / 24&quot; = 6314 RPM

160 MPH X 2.91 X 336 / 24&quot; = 6518 rpm.

Taking into account the slip of that Vega converter, I'd say that was somewhere in the ballpark.

Good times...very, very good times.

&quot; stock 7.5&quot; rear end&quot;

And how much longer did that rear live?

[bbbentley]

147mph M-B 6.3

[SS427]

145 plus mph between Pleasant Plains and Ashland, IL with Matt Murphy riding shotgun. We were driving Annie's #44 Phase III ZL1 and my 1st run to Ashland was about 130 mph and he promptly chewed me out and said it's top end was around 175/180 (not sure I believe that) so quit being a pussy. The return trip was about 145 plus mph (so I guess I'm a pussy). I had complained to him about some lifter noise and he wanted to hear it run so run we did.

I picked up my father in laws Ferrari 599 from the dealership in long valley, n.j. I was at 180 on the garden state parkway. I was able to drive that fast because I picked it up at 10 pm. I was only at that speed for a few seconds as the nj state trooper was way behind me with his lights on. He was ready to arrest me he was so mad. He was more upset when I told him I was best friends with a trooper a couple of steps below the top position. He wrote me up a broken taillight, although it was not broken. I didn't argue. I was wrong...but it was fun.it amazes me what formula one and stock car racers do for a living on the edge. Great reflexes!

I put a Vance &amp; Hines SS2R exhaust like that on the CBR900RR I mentioned in my post.

Which one? [img]<<GRAEMLIN_URL>>/naughty.gif[/img] [img]<<GRAEMLIN_URL>>/cool.gif[/img]

(I went through 3 or 4 rear ends in that car, but this was back when H bodies were still readily available in the junkyards and a complete boneyard posi rear end was only ~$100.00. The last one came out of a red, white &amp; blue Spyder)

*EDIT*

I found some old pics, sorry about the quality.

When I first bought the car, still had the anemic 262 in it.

2nd pic is during body work.



More body work and the first engine swap, a wheezer turd 327 that barely ran any better than the 262.



The bare block that became the 355 and a wheezer 350 that went in after the 327 expired.




The 355 shortblock and the car sitting out front after bodywork &amp; paint.
