Long block, newbie

[Davidless]

Hi all,
I was looking for some advice on a 427 for my SF roller almost on order.

At first I was going with a complete turn key full powertrain from one of the reputable builders. Looking at around 520+ hp. Then I came across a ford racing long block (M-6007-Z2427FFT back in stock) for around 14,800.

With most of the parts to finish as a full powertrain I calculated around 25g. I figured I’m more than capable of the completion since most of the precision stuff is done. Mech/mfg engineer here for the Gen V engine (LT4), with excess to a full machine and fab shop my brother has.

What I feel makes me want to go this route is a new updated Windsor block rather than the typical reconditioned out dated one.

I trust the ford people to build a decent LB engine with decent components because I know we do.

I can request a builder to use a dart or similar block, but think it may be much more than 25g total (full powertrain).

I also realize a reconditioned block is more than strong enough for 520 hp (from what I’m told) but it just bothers me for this amount of $$ I’d rather have an updated modern block, just me I guess. Plus better resale value, God forbid.

My definition of a full powertrain is carb, engine, clutch and trans to drop in, not including other hook up stuff like hoses and drive shaft.

It’s a winter project for me being newly retired, ie taking a buyout, and to chase women around or better yet, to get my mind off of them, lol.

Am I correct in my thinking or am I totally missing something?

Thanks for the help
