ryan and other small block gurus,, how about this guy??

james caro driver, car owned by sonny stancil

nhra super stock gt/ca
04 dodge stratus built by b and b race cars

360 59 degree block, .060 over, stock compression, which is 8.8/1 1.88/1.60 308 iron heads ported by me, edelbrock victor manifold ported by me. carter thermoquad carb. cam is around what you said on that other guys motor, but .670 or so lift.

car weighs 2750lbs with driver,, little less that your guy,, 9.47 at 139ish, 1/8 5.92 at 113.5.

this guy is almost knocking on that guys door, though 300lbs light,, doing it with waaayyy less quality of parts..

moral of the story,, if you spend good money and buy the right parts from the right people it isnt that hard to make something run like that.

Jeff, Those S/S cars are awesome, but run the #'s.... on the moroso calc 2750 @ 139 mph is 565 HP. Which is very impressive for the combo but over 100 shy of being anywhere near what I was talking about which was the most powerfull 59 degree head combo I have seen to date.

And for those throwing around big HP #'s like they are toys, we need a way to correlate one engine to another since all dynos spit out varying #'s and in many cases wildly varying. Ask Bigcube what the difference was Between Kent RItters SuperFlow and Dwaynes SuperFlow. I think anyone who builds and dyno's alot of motors soon realizes the vast differences that are out there. It's the uninformed public who buy into whatever # they are given, and that must be gospel. The best way I have found to corellate real world HP is vehicle weight and MPH. Granted you sometimes have to look at the air the car ran in to run the #'s the owner claims but usually you can get a good idea of what a motor is doing.

If anyone wants to post their Race weight and MPH I'll be happy to run the # through the moroso and tell you how it compares. Just for instance here is B3's 3350 lbs 134 MPH ~618 HP So it's no HP "king". It's nice combo that makes good power but is not exceptional, which is what we are talking about in this post.

MegaDart what was your race weight and best MPH with your old W5 motor? I'll let you know how it stacks up and don't be disapointed when it is no where near 740 HP. I think I did the #'s a while back when you had posted the weight somewhere and if I remember right it was in the 650 range. And you can argue all you want, I'm sure that motor did make 740 HP on someones dyno..... that's fantastic, but when the #'s are input against other known combo's it does'nt add up to 740 HP. Basically what I'm saying is you could have taken that motor to 5 other dyno's maybe 2 of them would show somewhere between 640-680 HP and 1 of them about the same 740, and 2 others maybe even higher. Those #'s are just #'s, the dyno is a tuning tool to try to extract the most power possible out of an engine, it's not a comparison tool. Vehicle weight and MPH is better comparison. BTW Your old Dry Sump system off the W5 motor is sitting in the shop, I'm building Chris Coco's 417" W8 motor currently. I did'nt realize that was your old 3 stage system until he sent me pics of it in the Dart.

Jerico: the '69's sitting in the main bay at the shop. It's about 1/2 painted, and is now a rolling chassis. Bodywork is taking longer than I hoped, and I wanted something to drive this summer, so I bought this '70 as a Driver. The '69's not going anywhere.

ANDYF: No I'm not saying this is the most potential power motor. I'm just saying I have yet to see or hear of one making more... I certainly think you could touch the 700 mark with a more "trick" combo. I just hav'nt seen anyone actually do it yet. Not alot of people want to spend $15K+ for a 59* head/59* block motor. They all just jump right to the 48* stuff and then big #'s are "relatively" easy.

If anyone else out there knows of a combo that they think is close, give me the MPH and weight and we'll see. I'm not saying this one is THE most powerfull out there, but from what I have seen it has got to be pretty close, certainly in top 1 percentile power wise of 59* motors.

And yes CBK I'm talking about "true" 59 degree motors, not 48* halfbreeds. I still will never see the "Fifty Nine Degree W9" as a real 59* head since it has 15 degree valve angle. In my mind a 59* head is a head that started life as 18 degree valve angle. I consider the 15 degree W2AB heads to be 48 degree heads, and so does MP.

And yes StrokedW7 and I talked to the guy with teh Green Dart at Norwalk two years ago. He said it had ran 9.40's 142 in the past, but was not hooking at Norwalk, we saw him go 9.60's @ 139. It was'nt taht he would'nt give out info, he just did'nt know anything about the motor. We asked what Stroke it had and he said I think it is 6". I said no... you probabbly mean it has 6" rod length. And he said yeah. After talking with him a little while I was able to extract taht it was a 9" deck R3, with a 3.80 Sprint car crank, 6" rod, 4.185 bore. It was a Davis motor and had Used Craftsman truck W8's on it. It had a "598" cast single 4 intake and some form of 4150 series Carb, I think it was a Demon off top of my head. It had a single stage belt drive oil pump. That's about all I remember. I believe he said the car was 3200 lbs with him. We asked about power #'s..... Maybe Steve remembers exactly what he said but it was somewhere in neighborhood of 840-860 PWR and 640 TQ.

3200 lbs @ 142 MPH = 700 HP. Which.... is about what we'd expct to see on Rider's dyno with that type of combo. So it made about what I thought it would. Around 700-720. Nothing spectacular, but about average for what it was. Some combo's seem to be over acheivers, some underacheivers and some are on average.
