    Jeff,

    I suspect you will get a ton of responses, but the last post to this thread was five years ago! 😁

    LOL i just noticed the same thing... I was going to Chime in and just talk about what we sell the most of, and also point out that the Build School uses BluePrint Engines.... but then saw this was 2014!

    Regardless...we go from 235HP to 541 HP...there's an engine for every customer.... all depends on wants/needs/budget.

    Last post on this thread almost 4 years ago. Person you're asking a question of hasn't been active on here for two years. Probably not the best approach.

    I personally don't have any experience with the MSD Atomic, but I have observed several builds using it. Over the last several years there are multiple similar throttle body EFI options. May want to consider a new thread.

    msmith,

    I have an aluminum 351w/427. Mine is based on the RDI "Z" block, basically what Ford Performance is now selling as their 351Z block but a bit different. AFR 225 heads, about 9.7 compression, .610 lift, 240 @ .050, 108 LSA, Vic Jr manifold, ProSystems 780, 1-7/8" custom headers. Somewhere around 440hp, 435 tqe on a Mustang chassis dyno, lots of runs. 535 hp on an engine dyno.

    There's about 65k on the motor but rebuilt it twice, once when a beehive valve spring broke and once after a front end crash that compromised the oiling system and jammed the throttle, not my fault. This is the motor that will go into my challenge car. It was in two different Superformance cars and I drive it hard.

    The RDI 427 weighs 400#, about 10# more than a 302/5.0 with Trick Flow EFI with similar accessories. BUT, the price you pay for aluminum is a bit high, might be a $4k premium over a similar iron block. I'd guess that a iron Windsor would weight 80-100# more, the RDI isn't a lightweight aluminum block.

    I'd do the same again but with more cam, compression and upgraded components. I think 600 at the flywheel is 'bout right.

    Hope this answers some of your questions.

    Jim

    Interesting so an all aluminum small block Windsor weighs 400 pounds, correct? I know an all aluminum 427 FE weighs 460. Just thought I would air that

    I weighed the two engines as available, then evaluated the collection of components on each and calculated a comparable level of completion. I don't think alternators, distributors and waterpumps were included.
