Keep everyone up to date with how your project is coming along.
Got a link to the actual cam card?
Not yet, This is a billet custom cam. I suppose that I will get it with the cam. I found it is extremely difficult to have contacts with performance shop or cam grinders and get some serious advices. I used to run Crane cams and they where there to help me on this one. Still waiting for Comp cam and others to wake up. The 55mm billet cores seem to be very special.
I wanted Something reliable for the street. Dyno will tell us where we are.
I just watched the Webinar concerning the head gaskets and wonder witch type to install. I used to run the FelPro Loc Wire composite gasket at 25+ PSI.
I concider now the Cometic MLS, but would those hold for 2000hp ? I am not sure I want to install copper gaskets, coolant sealing may by borderline in winter with cold start.
That's my last big question about the setup.
Nice fabrications, this proyect is going to see track testing or is highway porpose only ? which turbos are you going to use ?
Definitely an interesting proyect , I am following time back...
I will go to the dyno, track and highway.Would like to see some mid 8' . But this is mainly a street application
Turbos are PT7675 with the 0.96 turbine
Cylinder head air flow and turbos are capable for your HP goal, 1800 hp .
To make those cylinder heads flow around 380-400 cfm a 427 c.i engine have to spin around 8400 rpm and open the valves large quantities,
not an easy task on the engine building part of the proyect .
a 427 c.i @ 8400-8500 rpm and 25 psi of boost with your cylinder heads and the right components (camshaft, valve train, rotating assembly,etc)
could achive 1800 hp, but I think only a race car could manage all that power . Technically speaking since it is a street/strip car a little smaller
cylinder heads and turbos could be more usable , I am not saying that you are going to feel lag of torque and power on the low and mid rpm ranges ,
its impossible to feel insufficcient torque and power with that engine size ... as I say my comment is technically speaking .
Nice proyect to enjoy building and fun to test .
It could be interesting to see the cylinder heads flow/lift charts if you have it .
According to RFD the heads flow 410cfm, I measured them at just over email@example.com" on my flow Bench.
The valvetrain should do the job with T&D rocker shaft , 7/16 tappered pushrods, the springs at 300+ Lbs seat and 700+ lbs open pressure with Titanium valves (intake).
Those 2.20" valve weight 81g, compared to 128g for the 2.08" I had previoulsy in my Vic Jr heads. I start the build saturday, I will post pictures of those parts.
Keep it posting that powerful build ! post a picture of the car.
Nice Chevelle , interesting transmission setup . There is a drag Corvette in Poland with a similar transmission setup that goes high sevens
on the quarter "VTG Corvette" also they do a some others awd V8 . I always curious what transmission package , front differentials,
transfers and gearbox is apt to resist a high hp V8 turbo engine , once I looked a build that uses awd transmission of an off road
truck , maybe thats what all those setup are with some modifications ?
Attached are some pictures of my father 67 Chevelle with a stock 350 c.i engine 240 hp going to install a hot cam, headers and
maybe if time is friendly a little head work .
Nice headers, it looks like in little time is ready for brake in and dyno.
I think you better look for a awd hub dyno for the near 1600-1800 hp of your engine .
Nice runners and flange, plenum is going to be billet also? What its a man scs transfer ? perhaps a heavy duty machinary transmission?
It s going to be very interesting setup to watch it work .
First test drive is promissing. We went 5800rpm at 170kPa and already have 70% duty on the 2200cc injectors. This baby is breathing deep.
Nice, post some results and pictures when its possible.
I had to stop tuning and placed an order for a set of ID 2600cc. My 2200cc Bosch injectors went wrong after 6 months of E85.
This is what I have (fuel pressure test 30 PSI fully open). This week end I will perform a real test with pulses at my 60PSI car fuel pressure.
