The lift is certainly not the only thing to consider about the cam...what are the other specs?
BTW, what N/A 650HP 292 are you referring to? Cotton Perry's car made 549HP in the article I read (and also seemed to be pretty hard on itself). http://www.12bolt.com/inline_6_articles/cotton_perry
For a comparison, the Hot Rod guys later made 567HP with the same 454 on 91 octane (and 614HP on 114) with a solid flat-tappet cam. http://www.hotrod.com/how-to/engine/...lock-for-4000/
I guess part of it is also the application; your SWB stepside half-ton only weighs something like 3,500LBS and my truck weighs over 1,000LBS more than that at around 4,600LBS. To make matters worse, mine is also going to use a wide ratio truck trans and be asked to pull heavy trailers. |
I agree on the weight as well...In yer 1 ton..a big block would be the smart way to go...or a cummins diesel. ( lol) But on a C10 like mine...a 6 cylinder is plenty capable of making it an 11 or 12 second truck, which is what many small blocks can barely brag about....The cam I'm getting for my 292 is as follows: 268 duration 218 @ .050 .486 lift on a 110 lobe center.....bout .100 lift over stock and a little more duration...I believe the stock cam duration @ .050 was 186 and the advertised was 230 degrees..lift .371 on a 114 or 116 lobe center...But from your stand point...I can understand having a much heavier truck that more cubic inches and more cylinders helps...And that 650 hp 292 I was talking about is in the Inliner's Power manual...Known as the "No frills" 6...No specs on it really...But there's also the Mighty 6 pumping out some 1100 horse power...and it ran 8.44 at 157 in the 1/4 mile....it's beaten its fair share of small blocks for sure. lol But..Its running 30 pounds of boost...But when I get my engine done... I'll show ya that these little 6's can be a blast.
340 torque is plenty of power for a C10...Tom Lowe at 12bolt.com has a naturally aspirated 250 in his 66 chevy station wagon...some 4000 pound car with 2.57.1 rear axle ratio..and a 28 inch tire...he had that thing up to 100 miles and hour..and no..it did have to go across the US to get there. LOL!
