Re: QUestion about larger dispacement engine for FI I could spend 500 dollars and sh@t on your truck.Me spending 40k on my car....this coming from the guy who spent as much if not more than that to get his truck to run high 11's...congratulations!I know I would be stoked if I blew that much cash and got to run high 11's in a truck.....Not really.I would feel really bad if I spent 40k on a truck and had to spray a 200 shot to beat a bolt on car.

Re: QUestion about larger dispacement engine for FI A little angry aren't we. There is only one thing you left out though. I admit i did spend 40 to 45 thousand on my truck, but that is including the cost of my truck brand new as well as what i put into it. Not 40,000 addtional to what i already paid for the vechical. Just talking some s$$t. Give me a call when you wake up.
Re: QUestion about larger dispacement engine for FI this is a great thread and i would like to see more opinions, got a couple of things to add.
a 408 and a 422 will have the same bore, if you punch in the numbers a 4.030 x 4.0 = 408 and a 4.030 x 4.125 = 421. i think the 60 over with the big crank is a 427. lets forget about any heating issues for a moment and ask this question. a 422 is only something like $100 more than a 408 and has the same wall thickness, a $100 is nothing so the real question is which would make more power.
the 3/4 ton radiator is still just a one core but the surface area is huge.

Re: QUestion about larger dispacement engine for FI Well the only reason from keeping me from going witha 422 vs a 408 would be how much more would the piston want to walk with a .125 longer stroke? I have heard that the stroke to rod ratio of a 408 is actually better than the stock 346.WOuld the 422 actually be better than the 408? Or is the 408 pretty much as good as it gets? I am not planning on running a 3/4 ton radiator I will probably end up getting something like the SLP unit.

my situation is a little diferent than yours, i will probably have an iron block no matter what, so is it 370? 408? or 422? for me, all with 4.030 bore. figure unlimited amouts of intercooled boost(t88), what would be the quickest with pump gas/ with race gas?

Re: QUestion about larger dispacement engine for FI Why not look into something closer to what I have. I have an ARE resleeved aluminum block built for FI. The displacment is 415 with a 4.060 bore and 4" stroke. Basically I have the same sleeves as a 422, just .040 thicker for added strength.
I have the advantage of a light block with more sleeve material.
I had an iron block previously and I took it out. I never liked the added weight and you could feel the difference in the way the car plowed in corners. The new block made an excellent compromise.

Re: QUestion about larger dispacement engine for FI I really don't have a problem with the iron block so far, and I drive on skinnies all day long...

Re: QUestion about larger dispacement engine for FI Warbird cornering isn't an issue I need to deal with since this car will be street driven very limited and if I get caught not at all for 30 days if u catch my drift....Besides I believe that the iron block will be able to handle a higher amount of boost than an aluminum block.C5R is way too expensive for the benefits to justify the price tag, unless someone can prove me wrong.....

I will be running a max of 15 psi when I get the fuel sorted out but I wanted to point out that a big power, big displacement aluminum block can last if built properly.
Once again ARE runs 8.54 on their original 422 and that block has performed flawlessly for 50+ sub nine passes. Why add 100 lbs then have to figure out where to lose it later when you don't have to.
Just my $0.02

Re: QUestion about larger dispacement engine for FI Because I am getting a brand new iron block for $450. The darton sleeves around 1100,plus the block needs to machined to clear a 4.00 stroke,and the iron block will be able to handle way more boost.I should be able to run at least 25psi through it no problems.Besides the stock motor is going to be built up too only at a later date and it is only going to be like a 387,so I will eventually have a sleeved aluminum block also.
