Thread: I can't decide what engine to build....need advice

Tweet

WOW!!! Before I go any further, I must say this is the most awesome website I've ever found. A lot of sites offer very little help. You guys are awesome. That is almost exactly the engine comination I was looking at. I think the horsepower and torque numbers are very respectable for a streetrod. Heck, a lot of rods don't have half that much power. Couple of things.....I already have the performer RPM, the 981-16 springs required for the 282s cam so I'm well on my way to having all the parts. My headers are 1 5/8 block huggers. I'm sure the headers will hurt a little but I plan to upgrade to longtube at some point. I have already welded the flanges around the outside of the tubes and port matched them to the exhaust ports of the heads in an effort to get all I can out of them.. The heads have a 5 angle valve job, stainless valves w/ undercut stems and I believe a 30 deg. back cut. After much research, I tapered the guides and polished the ports, but I did not significantly alter the port shape. I was a little surprised at the flow numbers, they are a little low compared most. Nosing over at 5000 is also a surprise, though I do understand these are by no means new technology. The 700r4 does have a .7 overdrive and I have a lockup converter. 3.55's would put me at 2387 rpm at 80 mph and 3.73's would put me at 2508 rpm. WOW, 475 ft/lb's of tourque through a 3.06 first gear and 3.73's I better start thinking about a new rear suspension Thanks for your help, I really appreciate it. That's a lot of info!

You're welcome. I enjoy doing this stuff. You'll make more power than what was shown, because the heads will flow better than what I used in the DynoSim, but it's better in my opinion to show it conservative and be overwhelmed with the actual results than it is to anticipate something fantastic and possibly be disappointed with the actual results.
