Is it possible to get 300 hp from the original engine?
It is possible, but this car isn’t anywhere close to 300hp. A 300hp motor starting from a 3.0 block would be race-only. Very few people take a normally aspirated street-driven 3.5L to 300hp, let alone a 3.0.
Yes, but that would be a fullblown race engine, this particular engine does not have 300hp.
Edit, Markos was faster
Personally I already find these new prices exhausting.
Metric Mechanic bores to 3.7L with higher comp pistons to get 285hp and who knows what else. The eBay ad is deceiving.
Not arguing, just elaborating.
3.7L makes sense for a 3.5 core. I’m fairly certain that you can’t bore a 3.0 to 3.5+, and you also can’t stroke it all that much. The 3.0 does not have recesses in the block to account for the connecting rod clearance. You can machine the block a bit but not much. As mentioned, there are/were 3.0 race motors running 300hp+.
Long stroke reliefs cast into 3.3L+ blocks:
In ‘72 the Schnitzer green monster was running a 3020cc m30 with 290HP on mechanical injection and a slide throttle. It wasn’t street legal.
No underbody photos, claims to have rebuilt 5-speed
I agree Markos
If Korman had the car "from top to bottom", they are probably losing money at $89.9K...
And if it really has 43,000 original miles they are listing it low - this should be on BAT, with a poodle
Carb setup is definitely Korman...
kind of odd of the rear bumper rubber looks droopy?
Earlier I told my wife it was "downward dog"...she does yoga, I lean more towards yeast beverages.
Are they leaving $50k on the table or am I missing something?
It’s missing the large rubber blocks that mount behind the rear under riders on a 73.
looks like 50 to 100k on the table if it's a 43000 original mile car top to bottom restoration.
BTW, this is one of the first E9s that looks "right" to me on 16s. Nailed the tire size and stance.
Nice looking car. Can't speak to the miles. But based on this listing and another, I am making a mental note that what seems to be obvious - bumper orientation - seems to be harder to nail down than it seems?
I doubt that Korman did a "top to bottom" on this car considering the expense the PO of my car spent on the Korman stage 2 engine with the 3 DCOE 40 Webers.
This might have the Stage 4 engine that Montgomery Scott added the dilithium crystals in those carbs to pump out "around 300HP"......
