Hey Steff, just curious because I know basically nothing about those motors....What are the advantages to building one of those versus a big block?? Is it cheaper?? 
Hey Wayne, Big Block power in a lighter, smaller package? I dunno, I just love these motors and I'll never build anything else. Stock blocks holding up to good power....stock heads, cnc ported flowing 360+ cfm. Cost wise, good parts cost what they do regardless of platform. To me, it's build what makes you happy. These make me happy.
Thanx Guys!
Cool...How much power will that block safely handle? How many cubes can you get out of one? Are you running a stock oil pan? Can you buy headers and mounts that fit your car? 727 with adapter??
If you can't handle the truth, you're living a lie.......

your asking the wrong guy. Steff made almost everything. But to answer your question, you can buy almost everything you need to do a swap. 727/904 bolts right up just need a flexplate. Blocks are good past 1000

Hey Wayne, I made my headers and oil pan as I love making stuff, but like Gut mentioned, there's plenty of stuff available to put one in darn near anything. As for max cubes, I know a few companies make a 4.25 stroke crank and the largest bore in a stock block is in a 6.4 block...4.095. Mines at 4.100. I think the MP 6.1 Aluminum Block can go to 4.188 bore. A 727 or 904 Small BLock trans bolts right up. I'm using a Turbo 400 with a JW Ultrabell.

Looks good Steff. First chance I have had to look at video. Looks too loose in the front to me. I know you said you were putting a better shock on the front. I believe that will help it
Monte
Thanx Monte! If I make it out again this year, I'm going to tighten up the extension on the shock and sneak up on it, to where it effects the 60'. And yes, I'm going to get some new DA front shocks. I notice the front end bounces on the landing and I cannot adjust the compression as my Afco's are single adjustable.

It is projects like this that me consider building a gen 3 at some point. Looks and runs great. 70 Runners are the meanest looking cars in black.
Thanx Guys!

Heading out tomorrow for the last time of the year. Going to Darlington Dragway. Made a rear gear change from 4.57 to 4.86. May retard the cam timing a few degrees, to see what it does.
Also, Darlington is a 1/4 mile track, where all my previous testing was on an 1/8 mile track. 
Good luck Steff... get some good runs in

Managed to get one good pass out of 5 attempts today. Track prep at Darlington blows! First attempt blew the tires off. Loosened up the shocks 2 clicks and took 500 out of the t-brake launch. Worked for that pass. Ran 9.90 @ 133.3, 1.31 60ft. After that something changed. Tried a couple more times with few different shock settings and launch rpms and couldn't get it to repeat. I don't care. I got what I needed, which was where it traps in the 1/4, and to see if it liked the change from 4.57 to 4.86 gear. I think it did. The weather today was darn near identical to when I went out 2 weeks ago. I'll post video later.
Your one good pass got me tortured all the way home. Great meeting you today

Steff, congrats on putting together a great ride I wish I had your fabricating talents. The performance is great, and I am betting there is more in it, based on comparing the 9.90 ET to the mph. The computec predicts a mph of 137.63 for a 9.90. I don't know how much a full sized B body effects mph, but I doubt it is 4+ mph? Agsin,

Agsin,
Thanx Greg! I really appreciate the compliment. I was talking to HardcoreB yesterday. He said the same thing. I'm not sure where it's hiding.

Good work! What was your 1/8 mile on that pass compared to previous. Man that's a lot of gear, cool that the motor likes it
