Well, my engine is on the dyno as I speak and I should be getting some numbers tonight :grin: I was told it was started up and sounded like a very healthy big block, so hopefully the numbers will follow that. This engine sports the new 10.5:1 Wiseco pistons, 270 cfm flowing heads at .500 on the intake with 185 cfm on the exhaust, and a GS111 cam from Postons to compliment it all. Once the numbers are in I'll let you guys know asap. I'll see if Jim wants to put the specifics in as I'm sure you'll be interested.
Rob, Glad to hear your on the stand, and you know I am looking forward to the numbers(may just have to give Jim a call between his shifts,lol). From everything I have heard your small block may scare a few of the big block boys out there. And what it's like 100 + #'s lighter right ? Ohhhhh the possiblities.
I'm really excited with not just the fact that the engine is done, but the fact that I'll be able to drive my car for the third time! WooHoo! lol. When I bought the car off Scott Miller the engine was rebuilt by a Napa shop that is now out of business. The rebuild was 8 years from when I bought the car and Scott only put 1000 miles on it. Apperently, the Napa shop surely didn't know anything about clearences as the valves were kissing the pistons and an exhaust valve finally bent. So, after I started tearing the engine down I noticed shavings in the oil pan, which were more than likely from the bearings. After I found all of this I called Jim Burek as I remember Yardley was going through a rough time from the local guy he was using, so I figure I would spend the money for a reputable Buick shop. After thinking it over I decided to go all out as I wanted the car to perform, but I wanted to keep a small block in it as it's an original 350 4-speed. I figure the 455 route would be the easiest, but I wanted to be different. So, that's how this engine came alive today. As everyone who has dealt with Scott Miller, he's one of the very few people who's true to his word. I bought the car sight unseen, except through the photos he sent to me via email. I'm glad I bought the car as I don't have to worry about rust issues you find in the northeast. It was just an unexpected thing that happened with the engine that I'm sure alot of people have experienced. There's alot of money tied up in this car, but the first time I drive it I'll have the biggest smile on my face!:grin:
Hey Rob- I'm so excited for you! I know you've been waiting for those Wiseco pistons forever. Can't wait to hear the dyno numbers! :TU:
Well, I heard it on the phone. This engine sounds really healthy :grin: There's about 2 hours running time on it getting it broken in and soon the numbers will be up. We're going to see what this engine makes and then go from there. Jim thinks this engine can use a bigger cam than the Postons GS111, which is the hottest one they sell. He's going to get a baseline of how much horsepower this engine is pushing out and then improve from there.
Here are the baseline numbers... Well, Jim did three runs to see where we are starting at and the engine without being tuned and running a 1000 cfm demon carb that was taken off a 650+ hp 455 made 400 horsepower and 409 ft lbs. of torque. The torque came in at 3000 rpms which is really nice, but there's alot more power to be made as these are just baseline figures without the engine even being tuned in yet. He's using the TA Stage 1 intake first, then he'll use the Poston S-Divider with various carb spacers on both intakes.
Very Impressive baseline numbers for sure! :TU: How much power can the 350 handle and still be reliable???
Thanks Ken :TU: With the stock rods and block it should be able to handle 700 hp. The 350 is a Y-block design which offers alot of strength over the 455. The one thing we found out is the TA intake is holding the engine back with it's small intake runners. The dual plane design is holding air that the heads need. I guess when the intake was designed and built 20 years ago they never thought the heads would flow 270 cfm's.
I still can't believe that nobody makes a single plane intake for the 350! That should be the first new part someone should produce- even before heads.
A single plane intake will be made before the heads, but nothing will be made until the new 455 block and heads are done. Jim is going to try the Poston S-Divider later and see if that's an improvement, but he's far from done with the TA intake as he's trying various spacers to get the most out of it.
Is bulldog going to produce the intake? I didn't know there was a plan in progress. Nice numbers, by the way. Have you thought about a solid cam? Is Selingsrove anywhere near Ohio? I would like to see that car run once you have it together. Can't wait to see more fast 350's.
I'm around 4 hours from Ohio Just 15 miles south of I-80 at the 210 exit. The measurements Jim took of the cam were smaller than the advertised numbers. The intake lift measured 503.75 and the exhaust lift measured 511.5. The advertised lift was .520 for the intake and .523 for the exhaust. He feels there's more room for a bigger cam, but he wants to get the most from this one first. I was looking at the solid lift cams and seeing how they make more power than the hydralic ones. I think once he gets everything tuned in from both intakes he'll look at other cams if he feels there is more room for improvement. We're taking a list that is on top of the small block page for aluminum heads and single plane intake. I'm sure Bulldog would be involved with this, but the 455 stuff comes first.
Did I hear custom intake? This is good stuff... thanks for posting it! The 350 has to be the most under rated motor of all time.
Custom intake? no comment, lol.:Brow: Jim mentoned to me that a Hogan sheetmetal intake would be a $2000+ piece. I don't think I'm ready for that, but the current selection has the engine limited in making it's full potential. I feel if someone was to make a single plane intake that could handle high flow numbers it would be the hottest seller for the Buick 350.
