Re: help getting 400-450 hp
vortecs will not get you there.. maybe flywheel gross hp..
I'd look ad dart/afr/brodix 450 out of a n/a 350 is a tempermental beast.. you sure you can live with a set up like that |

Re: help getting 400-450 hp
an honest 400hp at the crank will even take decent heads if you keep streetable compression.

Re: help getting 400-450 hp
depends on budget. edelbrock performer rpm heads are decent street heads. i've seen lots of em used for $500-700 and they are legit 400hp. afr 185's are a better but then again will cost more. i would stay under 10.5:1 for premium fuel to be safe. people have run higher but cam selection becomes very important. also if you get some "bad gas" it could get ugly

Re: help getting 400-450 hp

Re: help getting 400-450 hp
you can do all you want up top and i dont understand why everyone always thinks in that direction. but i personaly would run the heads you have and put a 3.75 inch crank in it with corosponding parts and a good cam. you can always build the top later. It is usally the best way to go for the street. like most have said on here a 350 pushing 400hp is going to be a beast... but in my opinion a mild build on a 383 will get you 400 ponys no problem...

Re: help getting 400-450 hp
Yes the '95-00 350's were all fuel injected. But that doesn't mean you can't put a carburetor on it. Your block will have a date code on it. It will be located on the bellhousing flange just over towards the passenger side from where you found the 10243880.

Re: help getting 400-450 hp
Keep in mind, when you go with a longer stroke crank, you probably need to go with a new rod and piston as well to make everything work. But if you are going to do it, do it right. Make it stronger than your intended usage.

Re: help getting 400-450 hp
& as you step up in demand for air, (stroke, rpm or cubic inches) you need to revisit cam, heads, intake carb, exhaust..... your motor is a 'combination' of parts that can work together, and compliment each other, , or cost power, $'s and headaches.
I'd suggest you settle on a 'plan' and work forward towards that end.

Re: help getting 400-450 hp
if you have the money i sware by brodix and AFR both are great! but if your short on $$$ you could always take your heads out take em to a machine or motorshop and have them port them out, polish em and have them set up for bigger valves

Re: help getting 400-450 hp
the easiest way to help would be give us a budget goal. then let people help build a combo around that. you have to be honest/realistic what the engines use will be. then work from those points.

Re: help getting 400-450 hp
Oh I like that one.... a LOT!
They dyno test and match their components and you know they play well with each other! And the Edelbrock Vortec Performer RPM Air Gap should flow very well. If I had the means I would do it. So my vote would be to yes on this combo. But I did find this for your inspection. Trick Flow Super 23 465hp Top End Kit SBC K314-465-450 http://compare.ebay.com/like/2206128...=263602_304662
