Advice

Hi all,
wondering if I could get a bit of advice..
Time has come to start working on my dads XY, and want to take out the six that's currently in it and replace it with a 351, the purpose of the build is to drive it on weekends and the occasional strip too... rang Pavtek (cause I've been hearing there very good) and they gave me a quote to build a motor called the "SILVER ACCELERATOR" for $7,000 producing 445hp, now my question is do you think that this engine is too much for what I want or around the mark, is there another engine builder I can go to and get the same but cheaper (I also want the motor to be reliable)

Andrew

Re: Advice

7 sounds good to me for that power
the question of is it too much , thats up to you , you can get some sedate engines with that much power still , depends on cam / convertor / rear ratio/torque curve
ive never had that much power and im happy with MOST of the engines ive had ,some have been loud pigs even

Here's the >>Link<< for the motor, I've also copied the spec's

TORQUE: 431@4600 (SING, PLANE INTAKE)
TORQUE: 423@4200 (DUAL, PLANE INTAKE)
HORSEPOWER: 445@6000 (SING, PLANE INTAKE)
HORSEPOWER: 420@5700 (DUAL, PLANE INTAKE)
CAMSHAFT: Custom Pavtek Hydraulic
CYLINDER HEADS: 3V Small Port Alloy
COMPRESSION RATIO: approx 10:1
FUEL REQUIRED: Premium Unleaded
LONG MOTOR ASSEMBLED: L351C2/A $6990
SHORT MOTOR KIT: S351C2 $1631
ASSEMBLED HEADS: H351C3/A $CALL FOR BEST PRICE

APPLICATION
AN EXCELLENT COMBO THAT CONSISTS OF A CUSTOM HYD CAM / ROLLER ROCKERS & 3V SMALL PORT HEADS FOR EXCELLENT TORQUE & HP FOR THE ENTHUSIAST WHO WANTS REAL POWER GAINS BUT STILL WANTS TO BE ABLE TO DRIVE HIS OR HER CAR EVERYDAY. USING A DUAL PLANE INTAKE WILL ALSO ENSURE THAT BONNET CLEARANCE ISN'T AN ISSUE. COMBO REQUIRES THE USE OF A MIN. 2500 RPM CONVERTER & HAS A MILD TO LOPEY IDLE.


I should of rephrased the question.. sorry Pinkbits.. but I ment to ask if the price of the motor is too much\around the mark for the price there quoting

Re: Advice

I had a mate in NZ build up a 351 clevo in an XY for about $10000 and he had about 400hp, NZ is more exspensive for v8 parts so i would say the price is pretty good. But to be honest are you capable of building your own engine?
You could get a eng with the same pwr out put for a lot less as you wouldnt have to pay all there labour. I built a windser in NZ for my xy myself, it cost about $3000. Never got a hp reading from it but i was only margenly slower than his 10 grand clevo.

If you can build your own i would say do it, if you cant then it sounds like a good deal.

Re: Advice

The $ are right for the parts your getting. You can always up that engines hp pretty easy with a larger solid cam at a later date.

Re: Advice

i used to use any block i found with std bore but now id only use a block that was tested
some performance mobs sell blocks already sonic tested ( so you know the bore wall thickness is good and even )
here to sonic alone is about $200 , i think its a good investment
ive only used late model blocks which i get for nothing or very little
sometimes you may go through half dozen sonic tested blocks to find a good one so if i was offered one already done for 500 or so id buy it
i onlystart with std bore blocks
if you find a block with a rear main seal that is rope type and has the pin in it you usually know they havnt been stuffed with much
ive used blocks that have been flogged and overheated and it doesnt seem to matter much
i think ive rambled on for enough
