Questions on these heads.
Is this a good head for a primarily street 454 .030 over motor. 10:1 approx 240 duration, high 5-600 lift, 110 LSA solid cam. 66 Chevelle Th400 3.73 rear, 3800 lb car w driver,
On a 66 chevelle what are the chances of header fittment issues?
I just cant bring myself to re work my 781 heads to the approximate tune of $1000, so Im lloking to purchase aftermarket.
the ex port is up 3/4 inch ? your headers should work. i would use them. roller cam?

Here are the specs, and always willing to list to you and your input Pat...your opinion is always appretiated
Solid: 276/284 243/251 2 .050 586/600 lift 110 LSA
Solid Roller: 273/279 243/249 655/663 110 LSA
both are Lunati Cams. Not ;loyal to any one brand...just liked what I saw figuring a 3000 stall and 3.73 rear gears in a 66 Chevelle...figured it to be streetable and yet pull down some fun power for the track a few times a year...will possible add 100hp plate system as well.
hyd roller will work fine if you used a soild the crower with pin oiling are very good and crane you have to watch them. low rpm s low oil splash for a small cam any of the ones you list will work you just can not put them in they need to be wash in thinner a blow all the grease and set in oil before you put them in i have used soild rollers on the street for 20 years never have i lost one but i watch them and i not sit back till they fail i use erson cams .the roller cam looks ok i would not run a flat soild over a hyd or a soild roller cam has much better durability then flat lifter camQuote:
