stock replacement roller lifters are priced good but youll need spider and dog bones, if it had stock roller cam you coulda got it re ground and been a cheap roller motor build! should have 302 heads witch some love and others love to hate, but is a fine head for a mild 318 or truck motor, but nothing a stroker build would need!!! id rather have strong truly round 3.91 bores than thin weak 4 inch bores erry day of the week and twice on sundays!!
