Stage 1 is based off the off center production blocks but thats where it stops. It has the bosses for the extra bolts. The main webbing and alloy is far superior to the production crap. Unfortunately extra fasteners on the caps are not practical since the oil suction passage is there.
Still learning...
Are the production blocks that bad?
Were both stage 1 and 2 over-the-counter blocks?
When would it be logical to go to a stage 1 or 2?
I understand where you're coming from Bison. What amazes me is how much power some folks are making on a stock block, makes me wonder where the breaking point really lies, if they're really inferior.
Off the subject but I have an SG1 block laying around the garage and everyone thinks the thing is a stage block... I guess the fact that it has billet mains on it now could be confusing, I wish it was a Stage 1....
I am about 2 years away from building my motor so I figure I have a good amount of time to get this right. Iam looking to build a mid 10- car that is 99% street driven. I was planning on a stroked 109 But not set in stone yet. What's the difference in building a stroked 109 with forged everything and alum heads Vs a mid 10 stAge motor?
I dont know anyone who builds a stage 2 or TA and shoots for mid 10's. Aluminum heads are a waste at that level too. The cost to build the stage or TA will be about $5-6k more just to use the block.
Sorry Bison, we have built a few mid-10 TA alum blocks.
With the right combo, 10.0 at 17 psi boost, and a hydraulic roller cam is killer on the street, and last years with no major issue, like a blown head gasket.
There is only a couple hundred $$$ difference in building an alum block vs. a 109. Now is you add caps, girdle, etc. to a 109 block, then the difference to go with the alum block amounts to less than $2K.
What Bison says is true for the most part. But not all production blocks are made the same. Some were simply much thicker and stronger then others, by a lot! That's why a sonic test should be done before building a 109 to check the thickness.I understand where you're coming from Bison.

I didnt say it couldnt be done i said it wasnt worhtwhile. External oil suction and other unconsidered expenses. So how much for a TA off center 3.8 bore ready to go with everything except heads and intake? Forged crank and rods. PM me if you dont want to post it here
