There's a Vendor Directory tab at the top of the page so you can check when in doubt. I'm not finding them on there anymore though.

I bought the car and owned it less than 3 weeks before the motor blew, it was built by cartek in Georgia, needless to say I won't be using them ever again.
Sounds good...I think I can make this alot more manageable for you and help you achieve all your goals. The biggest questions are would you want me to build it for you or simply send you all the complimenting components for you to tackle the assembly yourself. Either way you end up with a killer optimized combination!

Hit me up this week....ring my mobile number when you have some free time and we can discuss in more detail. Afternoons and evenings are best for me....leave a message if I cant pick up the phone.....Im good at returning messages etc.

Cheers,

I would need the shortblock built at least so everything is properly align honed and all the clearances are set up properly. I'm an Aircraft mechanic by trade but obviously don't have the machining equipment to deck, cnc etc. I am capable of putting a rotating assembly together but I'd rather have the whole engine assembled by someone who does it every day, I would be very unhappy if I missed something and my motor failed. So I'll give you call and we can figure out the best plan of action. Thanks again Tony.

I'm curious, haven't been following the game closely enough for the past 3-4 years, what's the issue with the LS7 FAST? I've got an old (Mamo ported to my AFR 205s actually, done about 10 years ago) Fast 90/90 setup. Been starting to throw together a plan for an N/A big cube setup and was probably going to top it with a Fast 102.

Great thread BTW, OP please keep us updated I'm very interested in your build.

Issue with the FAST102 VS MSD (LS7 application) is that a Tony
Mamo ported (MAMOFIED) MSD makes 20+ RWHP VS Tony
Ported Fast 102, due to inherent design advantages of the MSD
INTAKE ( Larger Plenum, Shorter,Straighter Shot Runners) there
May be other advantages that Tony and/or others may elaborate
Further & better than I.

I see everyone talking about MAST 285 heads, why not the MAST 305's when they are the same price?

Because 285 CC is already a large port for a 427" street engine, go
To 305 CC and your port velocity below 3500 RPM especially
With a mid to high 240* duration intake cam will have poor
Throttle response (not to mention bucking and surging on the street) compared to a 265 CC Intake port that can flow
400+ CFM @ .600" (enough airflow for 800+ NA FWHP) and with
A low to mid 230* intake duration, still enough for 600+ RWHP
with a ported MSD and rip your head of throttle response to go
With very good driving manners.

Most guys are seeing 20-25 RWHP which needless to say is a really stout gain over (formerly) the best piece out there.

This thread has some results in it

http://www.corvetteforum.com/forums/...msd-gains.html

This one also...same scenario....FAST to one of my ported MSD intakes.

http://www.corvetteforum.com/forums/...-600-rwhp.html

I have these down to a science now having built some special tools/gauges to measure things as the porting work is getting done....I have done dozens already all of them with excellent results and feedback....alot more threads if you care to look on the Vette forum

So here's a question, ERL drysleeve block or a warhawk block? Pro's and cons to each. For the cost of the ERL drysleeve shortblock I can buy a warhawk block and callies rotating assembly and have my local shop put it together.

The ERL block is going to have longer sleeves.

I just cringe at the weight of a Warhawk or any really stout (heavy!) cast iron block.

Unless the goal was to make well into the four digits (where the weight isn't such a factor any more and the cast iron block improves ring seal from better structural integrity of the block), I would advise saving longer if necessary and going with a much lighter sleeved aluminum block.

Especially in a car that's more of a street car than an all out track car....weight negatively effects everything....handling, braking, ride quality etc.....its not just how much slower it may be in the quarter mile.

Just my .02....and I'm not sure what the OP is actually doing so these are just my observations/opinions in general
