Thread: 489 new here

ok im new but I need some advice

I have a mark iv 454 I been building I already have the rotating assembly its a scat set up with +3.00 cc pistons, I know now that I should have got some domes anyway im shooting for around 450-550 hp well in that neighborhood anyway more would be great but im a poor arse guy that makes 11.75 an hour,




#1 I was looking at heads 60489 made by edlebrock would they run the numbers im after for a street drivin, occasionaly drag raced 1986 sport coupe with a 4l60 or 4l80 or are their any stock castings that will keep a good compression ratio

#2 giving a set of heads ie the 60489's what cam would be good I cant afford a roller unless some one wants to give one away or I save for a while

thanks in advance for my lack of decision making skills 6 years ago when I bought the internally balanced 489 kit with +3.00cc pistons -cj



scat part #1-91505bi

4.280 bore
4.250 stroke
flat top single relief +3.00cc
cast scat crank
internal balance
rods 4340 i beam forged
stock mark iv block machined .030 over what is a good head cam combo that will make 450+ hp

I got the same kit this week but my scat crank was ground off center so am sending it back. Look at atk or blueprints web and see what they use for there combos and base it off there cams for there 496. Pay attention to the heads and compression ratio.
