Its Being Built

I know most of you were and are against building anything smaller than a 454 but I didn't want massive amounts of torque down low. The dyno sheet is from my machinist and every build they do gets done on the computer and those that also go engine dyno time are within 1 to 3% of the computer dyno.

I am having this 427 [.030 over] built for my use. My truck will see way more freeway time than street time and the cam is ground for mid-range and up power. Cam specs are mild by my standards lift .635/.635 duration at .050 is 233/245 on a 112, its a hydraulic roller cam to add to a longer life. I will be using SS rocker arms from either Norris or Crower since SS can handle the fatigue of being a daily driver better than aluminum [that and I don't trust aluminum rockers no matter how great they are].

The only stock item will be the bare block, its getting a full aftermarket rotating asy all forged and built to run on 91/92 unleaded. I will be using the smaller 265 AFR heads as the 290 heads did make more power but at the added expense of a 1000cfm carb which isn't in the budget [ I bought an 850 DP and single plane intake for $350, both with dyno time only of two hours].

As you can clearly see I'm still making over 500 on torque at 2000rpm.

He's getting me one more dyno sim of the 265 headed engine but with 1.8 rockers instead.


I'm sure your thinking this isn't a true budget engine which it isn't my parts total to around $6500. That's all I'm paying, its a trade build. His machining labor in trade for my paint and body labor.

Since we don't spend much time doing 500ci LS's, I'm in the "454 and under" corral

Besides, a little nitrous will make up for anything you feel like you didn't get.
Either way, looks like you'll have enough to have fun to say the least.

Re: Its Being Built

Well if I really got serious about racing it I would just switch to E85 and a big turbo

I think that's a great build! That's a daily driver monster! I built my shop truck engine (Pontiac) to pull a horse trailer and then to have fun at my local 1/8-mile drag strip (that's closing anyway). My build cost was just over $4500, doing some trading and scouring swap meets. It runs on 87 octane and backed with a 4L80E, it was getting 20 mpg on the freeway - supported by the brake specific at my cruising RPMs. I also have a 200 hp nitrous system just in case.

Re: Its Being Built

I love smaller cubic inch engines making big power. I love nothing more than a guy spanking someone and opening the hood to reveal those small valve covers.

Re: Its Being Built

^^^ I agree 125%

It's still why I fiddle with SBC's to this day.
