If i go turbo first, i can run like 7 psi to start and be at like 450 hp but will risk blowing my motor.... hmmmmmm, its really a question.... Do i need the power that bad that i can risk not having the money for more power later.... as in if i blow my motor it will take a ton of money to fix it so i wont have the money to make more power..... Right now it seems that motor first is best situation.... but other days i keep thinking i should go turbo first and get some power flowing!!! How about FLP trannys? Stage 4 or 5? Where can i buy those, are they def worth it? Ive heard good things

well i have that specific cam in my NA car now.all the car has is intake/exhaust and the cam and it made 350.so you figure with boltons and heads you could possibly see high 3--'s but why do you care what you make NA if your going to boost it down the road.so you make 340 NA now,still fun to drive,then when the turbos on you make 600+,have your cake and eat it too.
No I agree, theres no reason to dig into the engine twice, I just thought that lowering the CR that much would really effect the NA HP numbers significantly (like a 20% drop or so), and that doesnt seem to be the case. Thanks for the info!
Hmmmm. i want a 408...... can i get one fully built in my car for about 7 grand ish? Or whats the price? I jsut dont know how id build it tho.... build it with low comp for FI later or pure power now.....

You can get a 408 iron short block with forged internals from once of the sponsors for about $4000. You could also get a 402 forged aluminium short block for about the same. Youd then have to get a cam and all the valvetrain componenets, heads (figure around $2200 for afr 225's), then an intake (assum a fast 90/90 combo) and then injectors, etc...so its gonna be expensive. Im sure you can PM one of the sponsors, such as MTI or HPE or one of the other ones that builds engines and they can get you a quote for a complete longblock 408. Id guess though that any complete longblock, 402 or 408, is gonna be at least $7 grand if not more.

Verdad Gallardo that would be what i already stated.....APE also isnt a sponsor and screwed so many members on here.and you dont NEED AFR's but if your going all out go with either AFR ALL PRO or others have have a thicker deck if your making 1000rwhp or more.
Heres a link to the 402 short block:

and another 402 short block:

as for the 408 you can contact Texas-speed and they could quote you a price

HPE is whose doing my motor,theyve been awesome with me so far,and a friend who has the same motor as me is doing quite well atm. APE basically just took most peoples money and never sent a motor.
Wow what a bunch of ********. Yea I saw a few guys with some stuff about APE in their sigs and didnt know what happened, thats a shitty move though, especially by a sponsor. Yea I have only heard good things about HPE, what are you building right now, 408? Also, what are you using it for? Are you going turbo, spuercharger, or nitrous? I would love to have a 408, but im gonna start with camming my 346 right now (FM13 goin in real soon) and see how I like that. I was gonna forge my stock short block or go 402 or 408 and eventually a turbo but I dont get to the track a lot so im gonna start off with a cam and see how it fits my power needs/goals and go from there. No need to build a 10 second engine if I dont need it. My buddy though is actually getting his 402 short block from texas-speed. Hes not sure on the heads/cam combo yet but wants to spray a 250-300 shot (already has a direct port on a fast 90 intake on his 346 spraying a 150 shot).
what i was saying before is that as long as you are responsible enough to not push your motor further then you should you will be fine and not blow the motor. just get a good tune and run it safe and you will make plenty of power reliably.
that way you can have your power you want now, and save up for a motor. if you buy the motor now, ya, it will be forged, but you will get antsy and want to do something to it.
Thats just my 2 cents.

just dont screw around with your tune or kiss the motor in the car now goodbye...another point is was trying to bring out is that you have like no down time the way i was saying and other are saying.which is always good for a DD.
as far as the tranny look in the boosted lists and see what others are running and follow suit tailored to you needs.

Hmm yea.... well i would really like to have a big ol rumpy engien with huge ehads and a cam and sick n/a power but if i go that route than i cant turbocharge it or anything and that will get to me. Im sure 500-550 would be mroe than enough for the street and im sure if i get a low comp motor and turbocharge it ill kill myself. I mean exactly how safe is anything only 750 hp o nthe street? What will i need to get ANY sort of traction? haha man.... Is there any comprimise here, like a decently low comp motor where i can have about 475 NA and still turbocharge it later or what? Also what head/cam choice do you guys suggest for me NA for both..... if i were going to turbo later.... what comp ratio, heads/cam would you suggest? And if i were jsut shooting for a big NA numbers, what comp ratio/heads/cam would you suggest? Im gunna PM HPE and Futral now and get some sort of prices going. Thanks men. Maybe ill make a post..... to build 408 for street..... build it for turbo later or made NA now and forever

Nice, yea I mean again its all in what type of car your looking to build. Just out of curiosity have you ever been in a 500+ rwhp car? Before my buddy blew his engine he was running his stock 346 block with a 231/237 cam and a 150 NX wet shot, which put down 500+ rwhp and 500+ rwtq and that thing was a monster! It pulled like a bat out of hell, and traction on the street was pretty much non-existant since he didnt have the proper suspension/traction mods, such as some nice sticky tires, a 12-bolt, etc...He went for the power first, then blew his engine, and now he is rebuilding it with a forged 402, moser 12-bolt with 35 spline axles, and it looks like a th400 (if he can afford it). This is why im starting with a cam first, see how I like it, then im gonna go from there. If you look around the forum there are plenty of heads/cam and even cam only cars dipping into the 11's in the 1/4, which is friggen fast! If you havent been in a car with that much horsepower before Id say stop by Exotic Performance Plus and see if Bob or one of the other guys can give you a ride in one of their modded cars and let you decide how much power you really need.
